The Rose of Persia: An Ancient Legacy
Few flowers carry the weight of history and poetry that the Persian rose does. For millennia, the rose has been the defining symbol of Iranian civilisation — threaded through the verses of Hafez and Rumi, pressed into the pages of illuminated manuscripts, distilled into the attar that perfumed the courts of the Achaemenid kings, and painted with delicate precision onto tilework that still adorns mosques and palaces across the Iranian plateau. The word “paradise” itself derives from the Old Persian pairidaeza, meaning a walled garden, and within those ancient enclosures, roses were always the crown jewel.
The relationship between Persia and the rose is not merely ornamental. It is botanical, agricultural, medicinal, philosophical, and deeply spiritual. The Persians were among the first peoples to cultivate roses with systematic intent, selecting for fragrance, colour, and form over hundreds of generations. The result is a tradition of rose culture that gave the world many of its most beloved varieties, including the foundational ancestors of the modern hybrid tea and the old garden roses that European growers prized so extravagantly.
This guide explores the unique, rare, and historically significant Persian rose varieties that have shaped world horticulture and continue to be cultivated in Iran today — from the famous Rosa × damascena fields of Kashan to the wild species climbing the slopes of the Alborz Mountains.
Part One: The Wild Roses of the Iranian Plateau
Before cultivation, there was wildness. Iran sits at a remarkable botanical crossroads, where the floral diversity of the Caucasus, Central Asia, and the Indian subcontinent converges on a landscape of extraordinary topographic variation. Deserts, steppes, temperate forests, alpine meadows, and sub-tropical coastlines exist within a single national boundary. This variety of habitat has nurtured a remarkable diversity of wild rose species, many of which form the genetic foundation of cultivated Persian varieties.
Rosa persica (The Persian Yellow Rose)
No rose is more distinctly Persian in its identity than Rosa persica, known in Farsi as gol-e zard-e irani — the Iranian yellow rose. Botanically speaking, this plant is so unusual that it was long classified in its own genus, Hulthemia, before being reintegrated into Rosa by modern taxonomists. It remains the only rose species to bear a flower with a red blotch at the base of each petal on a bright yellow ground — a pattern so distinctive that breeders have spent decades trying to introduce this characteristic into garden hybrids.
Rosa persica grows wild across the arid highlands of Iran, Afghanistan, and Central Asia, preferring gravelly, well-drained soils in semi-desert conditions. Its stems are distinctive too — bristly and almost spineless in the conventional sense, with small, often undivided leaves that distinguish it sharply from other roses. The flowers are tiny by garden standards, rarely exceeding three centimetres across, but their colour and marking make them immediately recognisable and unforgettable.
For centuries, this rose defeated all attempts at hybridisation. It proved almost impossible to cross with other rose species because of differences in chromosome structure and flowering habit. It was only in the latter part of the twentieth century, after painstaking work by breeders in Europe and America, that a series of hybrids began to emerge under the group name Hulthemosa, which successfully introduced the red blotch into larger-flowered plants. Despite this, Rosa persica itself remains a challenge to cultivate outside its native semi-arid habitat. It dislikes winter wet and excessive summer humidity, making it notoriously difficult in northern European gardens, yet it thrives in the conditions that shaped it — the baking summers and cold, dry winters of the Iranian interior.
Rosa foetida (Austrian Briar)
Despite its misleading common name, Rosa foetida is native to western and central Asia, with a primary distribution across Iran, Turkey, and the Caucasus. The “Austrian” designation crept into botanical nomenclature through the European trade routes by which the plant reached Western horticulture in the sixteenth century. In Persia, it was long cultivated in two forms: the straight species, which bears vivid, almost harsh yellow flowers, and the form known as Rosa foetida ‘Bicolor’, which displays petals that are yellow on the reverse and copper-orange on the face — one of the earliest bicoloured roses known to cultivation.
Rosa foetida is the ancestor of virtually every yellow and orange-toned rose in modern horticulture. When the French breeder Joseph Pernet-Ducher succeeded in crossing it with hybrid perpetual roses at the end of the nineteenth century, he introduced the colour range of yellow, apricot, copper, and flame into the genetic pool of the hybrid tea rose, essentially creating what became known as the Pernetiana class. This single breakthrough, built on a wild Persian species, transformed the palette of the modern rose garden.
The flowers of Rosa foetida are semi-double in the cultivated forms, bright and showy, opening flat to reveal golden stamens. The fragrance, however, is complex and to some noses unpleasant — a fact reflected in the Latin epithet foetida, meaning “ill-smelling.” To others, it has a rich, oily quality reminiscent of certain herbs. The plant is vigorous and arching in habit, producing its flowers in a single spectacular flush in late spring, and is notable for being susceptible to black spot, a trait it unfortunately passed to many of its descendants.
Rosa glutinosa (Sticky Rose)
Found in the rocky limestone formations of northern and north-western Iran, Rosa glutinosa is one of the lesser-known wild species with botanical interest. Its common name derives from the sticky, glandular secretions on its leaves and sepals, which give the plant an almost resinous fragrance when touched — quite unlike the sweet floral scent of the petals. The flowers are small and pink, and the plant forms dense, compact thickets that make it potentially useful as a wild hedge plant.
Ethnobotanically, this rose has been used in traditional Iranian medicine, with the hips being employed for their high vitamin C content and the leaves prepared as poultices. It has received little attention from international breeders, partly because its ornamental qualities are modest, but it represents an important component of Iran’s native rose flora.
Rosa canina (Dog Rose) — The Iranian Ecotypes
Rosa canina, the dog rose, is widespread across Europe and western Asia, and the populations found in Iran constitute a fascinating series of ecotypes that show considerable variation in flower colour, hip shape, and plant habit compared to their European counterparts. In the forests of the Caspian slope — that narrow, humid strip between the Alborz Mountains and the Caspian Sea — dog rose populations have evolved in conditions very different from the dry Mediterranean and continental climates where this species is often found further west.
Iranian ecotypes of Rosa canina tend to have larger, more deeply coloured flowers, often trending towards deep pink rather than the pale blush of typical European plants. Their hips are frequently larger and more elongated, and the plants can reach extraordinary heights when scrambling through the tall forests of oak, hornbeam, and box that characterise the Hyrcanian region. These populations have been used in traditional medicine and confectionery for generations, with the hips cooked into jams and syrups that are sold in the bazaars of Rasht and Sari.
Part Two: The Cultivated Heritage — Ancient Varieties of Iran
Rosa × damascena ‘Gole Mohammadi’ (The Prophet’s Rose)
The centrepiece of Iranian rose culture, known as Gole Mohammadi — the flower of the Prophet — is the form of Rosa × damascena that has been grown in the fields of Kashan and the valleys of the Zagros Mountains for at least a thousand years. This is the rose of Iranian poetry, the rose whose fragrance fills the air of Kashan’s villages every spring, and the rose from whose petals the finest Persian rosewater and attar are distilled.
Gole Mohammadi is a medium-growing shrub reaching approximately 1.5 metres in height, with prickly stems and foliage of a greyish-green. The flowers are typically semi-double to double, opening from pointed buds to shallow, quartered blooms of clear pink, the petals arranged in a rosette pattern around a small central cluster of golden stamens. The fragrance is the defining quality: intensely sweet, true rose, deep and complex, with warm undertones of something almost spiced. It is this fragrance that the perfume industry has sought to capture and replicate, with only partial success, in synthetic rose compounds.
The cultivation of this rose in the Kashan region, and particularly in the town of Qamsar and its surrounding villages, is one of the great agricultural traditions of Iran. Each spring, when the rose harvest begins in May, the entire landscape is transformed. Pickers work in the early morning hours before the heat of the day can diminish the essential oils, stripping the petals by hand into large cloth bags. The petals are then processed almost immediately into rosewater by steam distillation — a technique that the Persians developed and refined and which, when it reached the Arab world and eventually Europe, transformed both perfumery and cooking.
The specific Gole Mohammadi variety grown in Kashan has characteristics that distinguish it from other Rosa × damascena populations found elsewhere. Local growers speak of its particular floral richness, and research has confirmed that the essential oil profile of Kashan-grown damascena differs measurably from that of Bulgarian or Turkish specimens of the same species. Whether this reflects genetic differences between the populations or simply the effect of the unique soil and climate of the Kashan region — or both — remains a subject of continuing investigation.
Rosa × damascena ‘Isfahan’ (The Rose of Isfahan)
The city of Isfahan, once the capital of the Safavid empire and among the most beautiful cities in the world, lent its name to a rose variety that has been grown in its gardens since at least the seventeenth century. The Isfahan rose, also sometimes called the Ispahan rose in European catalogues, is a Rosa × damascena form that differs from the Kashan Gole Mohammadi in several respects.
The Isfahan rose tends to produce flowers of a warmer, slightly deeper pink, with a more fully double bloom of many petals that open in a lax, luxuriant manner. Its fragrance is exceptionally rich, perhaps even more intensely perfumed than the standard damascena forms. The plant is notably vigorous, capable of reaching two metres or more when grown on a support, and it has an exceptionally long flowering season for an old rose — in Isfahan’s climate, it may produce a primary flush followed by intermittent flowers throughout the growing season, an unusual characteristic for a once-flowering damask.
The Isfahan rose reached European cultivation at some point in the eighteenth century and became a beloved variety in French and English gardens, where it was treasured for its extraordinary fragrance. It remains available from specialist old rose nurseries and continues to be grown in the historic gardens of Isfahan itself, where it is part of a living horticultural heritage that connects the present to the imperial gardens of the Safavid period.
Rosa × centifolia — The Persian Origins of the Cabbage Rose
The cabbage rose, known botanically as Rosa × centifolia, is a complex hybrid of obscure origin that has long been associated with the Low Countries of Europe, where Dutch and Flemish breeders of the seventeenth century are traditionally credited with its development. However, the ancestry of Rosa × centifolia is almost certainly Persian, and the variety’s genetic composition traces back to damask and Gallic roses that were themselves derived from Iranian breeding traditions.
In Iran, roses of the centifolia type — densely double, round-budded, with petals folded one upon another in an almost mathematical progression — are referred to in historical sources as sad-barg, meaning “a hundred petals.” This term appears in Persian poetry from the medieval period onward, suggesting that highly double roses of this type were known and cultivated in Persia long before they appear in Dutch paintings of the golden age. Whether the European centifolia was independently developed or descended from Persian material brought west via the Ottoman trade routes is a question that botanical historians continue to debate.
The sad-barg roses grown in traditional Iranian gardens today vary considerably in character. Some are compact and rounded, with flowers of the palest pink shading to near-white at the centre; others are larger and more informal, with petals of medium pink that fade attractively as they age. All share the characteristic dense doubling and the rich, sweet, somewhat powdery fragrance that distinguishes roses of this lineage.
Part Three: The Rose Gardens and Regional Varieties of Iran
The Kashan Tradition
Kashan is the undisputed centre of Iran’s rose culture, and the rose gardens of the region constitute one of the world’s most important living repositories of traditional rose varieties. The rosestan — the rose garden — has been a feature of the Kashan landscape for at least a thousand years, and the knowledge of rose cultivation, harvesting, and distillation has been passed from generation to generation in the villages of the surrounding plain.
Within the Kashan tradition, growers distinguish between several named selections of Gole Mohammadi that have been maintained by specific village communities. These local varieties differ from one another in subtle but agriculturally significant ways: some are said to produce a greater quantity of petals per flower, making them more economical for rosewater production; others are valued for a particular quality of fragrance; still others are noted for their robustness and resistance to late frosts. These selections have never been formally catalogued or given botanical variety names, but they represent a form of folk breeding of great value — a living gene bank of Rosa × damascena diversity maintained by the practical knowledge of farming communities.
The Shiraz Rose Tradition
In the south-western city of Shiraz, historically associated with wine, nightingales, and poetry — particularly the verse of Hafez, whose tomb stands in a garden filled with roses — a distinct rose culture developed alongside the literary one. Shirazi roses are mentioned in the works of Hafez himself, who uses the rose as his central symbol of divine beauty and earthly desire. The nightingale (bolbol) lamenting its love for the rose is perhaps the most persistent trope in all of Persian poetry, and in Shiraz this image has a particularly vivid local grounding.
Traditional Shirazi rose cultivation emphasised varieties of intense fragrance over those most suitable for commercial rosewater production. Roses with unusually deep pink or crimson flowers were particularly prized, and some varieties grown in the old walled gardens of Shiraz show colour characteristics not typical of the damascena varieties dominant in Kashan. Whether these represent distinct genetic lineages or simply local selections of the same species influenced by the different climate and soil of the Shiraz region remains to be determined by detailed botanical study.
The Roses of the Caspian Region
The narrow, humid strip of land along Iran’s Caspian coast — the provinces of Gilan and Mazandaran — possesses a rose culture quite distinct from that of the arid interior plateau. This region’s climate, with high rainfall, mild winters, and warm, humid summers, supports a different range of rose varieties, and the proximity of the Hyrcanian forests has maintained a more diverse wild rose flora than exists in most of the country.
In this region, wild and semi-wild roses of the Rosa canina complex have long been used alongside cultivated varieties in the production of rosewater and the extraction of hips for culinary and medicinal use. The roses grown in village gardens here tend to be more vigorous and less carefully selected than those of the Kashan distillation tradition, reflecting a different set of priorities: robustness, adaptability to humid conditions, and the production of large, vitamin-rich hips as much as the quality of the flower.
Part Four: The Persian Rose in Perfumery and Distillation
The Art of Attar Extraction
The Persian tradition of extracting the essential oil of roses — known as attar of roses, or attar-e gol in Farsi — is one of the most significant contributions of Iranian culture to world perfumery. The method of steam distillation that produces attar was refined, if not invented, by Persian chemists and physicians of the medieval Islamic golden age. The scholar Ibn Sina (Avicenna), writing in the eleventh century from a Persian cultural context, provided some of the earliest systematic accounts of the distillation process, and the technology spread westward through the Arab world to reach Europe in the centuries that followed.
True Persian attar of roses is among the most expensive natural perfumery ingredients in the world. The oil content of rose petals is vanishingly small — it takes somewhere between three and five tonnes of petals to produce a single kilogram of pure attar — and the extraction process is labour-intensive, requiring the processing of petals within hours of picking to prevent the volatile aromatic compounds from degrading. The essential oil of Rosa × damascena contains hundreds of chemical compounds, the most important of which are geraniol, citronellol, nerol, and the uniquely rose-specific molecule beta-damascenone, which gives Iranian attar its characteristic warm, deep, almost honey-like quality.
Persian attar differs measurably in its chemical profile from Bulgarian attar produced from the same species, and perfumers working with natural materials treat them as distinct ingredients. The higher altitude and drier growing conditions of the Iranian plateau are thought to stress the plants in ways that increase the concentration of certain aromatic compounds, resulting in an oil with a more complex and persistent character.
Rosewater: The Foundation of Persian Culture
If attar is the luxury product of Iranian rose culture, rosewater is its everyday foundation. Ab-e gol — rosewater — permeates Iranian life in a way that has no direct equivalent in any other culture. It flavours the rice dishes of Persian cooking, sweetens the desserts, perfumes the sherbet drinks served at celebrations, and is sprinkled on guests as a gesture of welcome. It is used in religious rituals, in traditional medicine, and in cosmetics. The rosewater used in the Kashan and Shiraz traditions is far more concentrated and aromatic than the dilute rosewater sold in Western supermarkets — a teaspoon of good Iranian rosewater can transform a whole dish in a way that would require many tablespoons of the commercial product.
The rosewater distilleries of the Kashan region — known as gol-abdan — are ancient in character, though some have been modernised. Traditional distillation uses large copper vessels called deg, in which petals and water are heated over wood fires. The steam, carrying the aromatic compounds of the petals, passes through a copper pipe cooled by cold running water, and the condensate — rosewater — collects in vessels at the far end. This technology, essentially unchanged for centuries, continues to produce a product of extraordinary quality.
Part Five: Medicinal and Culinary Rose Varieties
The Medicinal Tradition
Persian medicine, codified in the great texts of Avicenna and Rhazes, attributed extensive therapeutic properties to the rose. Gole Mohammadi and related varieties were used in treatments for conditions ranging from digestive disorders to eye infections, from anxiety and depression to skin complaints. The petals, dried and powdered or prepared as a decoction, the hips, rich in vitamin C and antioxidants, the distilled rosewater, and even the thorns and leaves all found their place in the pharmacopoeia of traditional Iranian medicine (tebb-e sonnati).
Of particular note in the medicinal tradition is the emphasis on varieties with the greatest fragrance concentration, on the understanding that the therapeutic properties of the rose were bound up with its essential oil content. This means that the varieties selected for medicinal use overlapped substantially with those used in the perfumery tradition — the Gole Mohammadi of Kashan was valued as much by the physician as by the perfumer.
Specific rose varieties grown for medicinal purposes in different regions of Iran include selections with particularly deep-coloured petals, which were associated in traditional medicine with a greater concentration of active principles. Deep crimson forms of Rosa × damascena, grown in some villages of the Zagros foothills, have been used in traditional preparations for centuries and have attracted some modern phytochemical research interest.
The Rosebud and Its Culinary Uses
In Iranian cooking, both rosewater and dried rosebuds (ghonche) are important ingredients. The rosebuds used in cooking are typically dried before they fully open, preserving both their colour and a concentration of aromatic compounds that would be partially dispersed if the flowers were allowed to bloom. These dried buds are used in rice dishes — particularly the celebratory rice shirini polo — in jams, in the spice mixture advieh, and as a garnish and flavouring for tea.
The rose varieties considered best for culinary use are those with the most complex and lasting fragrance and the deepest, most stable petal colour after drying. Certain selections of Gole Mohammadi grown in the villages around Kashan are specifically cultivated for the bud trade rather than for rosewater production, the farmers harvesting the flowers before they open rather than at full bloom. These culinary rosebuds are traded across Iran and exported to Iranian diaspora communities around the world, where they are used in the preparation of traditional Persian dishes.
Part Six: Heritage and Modern Conservation
The Threat to Traditional Varieties
The rose varieties that have been cultivated in Iran for centuries face increasing pressure from modernisation, economic change, and climate variability. The labour-intensive nature of traditional rose cultivation makes it economically marginal compared to other agricultural activities, and younger generations in the rose-growing villages of the Kashan region have increasingly sought employment in urban centres. Some of the most localised and distinctive traditional varieties — the unnamed selections maintained by specific farming families across generations — are at risk of disappearing as the human knowledge that sustains them is not passed on.
Climate change presents an additional challenge. The semi-arid conditions of the Iranian interior are already marginal for agriculture, and shifts in rainfall patterns, rising temperatures, and more frequent late frosts threaten the timing and reliability of the rose harvest. The relationship between the Gole Mohammadi and its particular environment — the altitude, the specific pattern of cold winters and warm springs, the mineral composition of the soils — means that even relatively small climatic shifts can affect the quality and quantity of the harvest significantly.
Conservation Initiatives
Awareness of these threats has prompted both governmental and non-governmental conservation initiatives within Iran. The Agricultural Research, Education and Extension Organisation (AREEO) has established a rose gene bank at its research station in Kashan, collecting and documenting accessions of Rosa × damascena from villages across the region. This collection preserves genetic diversity that might otherwise be lost if individual village populations disappear from cultivation.
International botanical institutions have also recognised the importance of Iranian rose heritage. Several European botanic gardens maintain collections of old Persian rose varieties obtained from Iran over the decades, and specialist old rose nurseries in France, England, and the United States have preserved varieties like the Isfahan rose that might otherwise exist only in historical literature.
Within Iran, a growing movement of cultural tourism around the rose harvest season has created new economic incentives for traditional cultivation. The annual Jashne Golabgiri — the rosewater festival — held in Kashan each May has become a significant cultural event that attracts visitors from across Iran and from the Iranian diaspora, creating a market for traditionally produced rosewater and attar that supports the continuation of heritage cultivation practices.
The Role of Botanical Research
Modern botanical and genetic research is beginning to shed light on the relationships between Iranian rose varieties and the broader taxonomy of Rosa. DNA analysis has confirmed that Rosa × damascena is a complex hybrid of ancient origin, with genetic contributions from at least Rosa gallica, Rosa moschata, and Rosa fedtschenkoana, the last of which is a Central Asian species that is thought to be responsible for the repeat-flowering characteristic found in some damascena populations.
Research on the wild rose flora of Iran is also ongoing, with botanists documenting the distribution and diversity of native species across the country. The Hyrcanian forest region has been identified as a centre of wild rose diversity, and several undescribed or poorly known taxa may await formal scientific recognition in the remote mountain valleys of the Alborz and Zagros ranges.
Part Seven: Growing Persian Rose Varieties
Climate Considerations
The roses of Persia evolved in a range of conditions that differ significantly from the temperate maritime climate of north-western Europe or the humid subtropical conditions of parts of North America. The wild species of the Iranian interior experience hot, dry summers and cold, often dry winters — a continental pattern that makes them well-suited to the gardening conditions found across much of the United States, Central Asia, and the drier parts of southern Europe.
Rosa persica and Rosa foetida are among the most drought-tolerant of all rose species and should be grown in the driest, sunniest positions available, with excellent drainage and minimal irrigation once established. They dislike the wet winters of oceanic climates and are prone to fungal problems when grown in persistently humid conditions.
The cultivated Persian varieties, particularly Gole Mohammadi and the Isfahan rose, are somewhat more adaptable, having been selected over centuries for garden cultivation. They perform well in continental climates with cold winters and warm, relatively dry summers. In the moister climates of England and northern Europe, they can be grown successfully but benefit from an open, sunny position with good air circulation to minimise the risk of fungal disease.
Soil and Feeding
Persian roses are generally less demanding in terms of soil fertility than modern hybrid tea roses, which have been bred for heavy, repeated flowering and require intensive feeding to perform at their best. Wild species like Rosa persica and Rosa foetida actually perform better in relatively poor, well-drained soils, and excessive nitrogen fertilisation will produce lush vegetative growth at the expense of flower production.
The cultivated damask varieties benefit from a moderate application of well-rotted organic matter incorporated into the soil at planting, and an annual top-dressing of compost in autumn or early spring. Specialist rose fertilisers can be used but are not essential; the emphasis should be on maintaining healthy soil biology rather than forcing growth with inorganic nutrients.
Propagation
Traditional Persian rose cultivation has always relied on vegetative propagation rather than seed, since named varieties do not come true from seed and the unique characteristics of each selection can only be preserved by propagating from cuttings or by layering. The traditional method used in the Kashan region is layering — bending a long cane to the ground, partially burying it, and allowing it to root before severing it from the parent plant. This is a reliable and straightforward technique that produces vigorous, own-rooted plants.
Hardwood cuttings taken in autumn are also effective for most damask roses, though success rates vary. The cuttings should be of pencil thickness, taken just below a bud node at the base and just above one at the top, and inserted into a free-draining medium in a sheltered position outdoors. Own-rooted plants produced by this method tend to be more resilient and longer-lived than grafted specimens, and they have the advantage of producing suckers true to variety rather than throwing rootstock growth.
Pruning
Persian roses, particularly the once-flowering damask varieties, require a different approach to pruning than modern repeat-flowering roses. Since these roses bloom on wood produced the previous year, the timing of pruning is critical: cutting back hard in early spring, as is appropriate for hybrid teas and floribundas, removes precisely the wood that will carry the season’s flowers.
The correct approach is to prune Persian roses immediately after flowering, removing the flowered stems back to strong young growth that has emerged from the base or from lower on the plant. This allows the maximum growing season for the new wood, which will carry next year’s flowers. A light tidying can be done in late autumn to remove dead wood and reduce the risk of wind damage, but major pruning should always be reserved for immediately post-flowering.
Conclusion: The Rose as Cultural Monument
The roses of Persia are more than garden plants. They are living monuments to one of the world’s great civilisations — botanical artefacts that carry within their genetics the accumulated knowledge and aesthetic judgement of hundreds of generations of growers, poets, physicians, and perfumers. To cultivate a Gole Mohammadi or an Isfahan rose is to participate, however humbly, in a tradition that stretches back through the ages, to gardens watered by ancient qanats, to the rose fields that scented the courts of the Safavid shahs, to the mystic gardens of which Hafez and Rumi wrote when they sought earthly metaphors for divine love.
The diversity of Persian rose varieties — from the tiny, blotched flowers of Rosa persica scrambling over desert gravel to the extravagant, fragrance-laden blooms of the cultivated damask forms — represents a genetic and cultural heritage of global importance. Its preservation is not merely a matter of horticultural sentiment. It is a responsibility to the richness of human agricultural history and to the future possibility of rose breeding that can draw on this deep well of diversity.
In the villages of Kashan, the rose harvest continues each May as it has for a thousand years, the pickers rising before dawn to gather the blooms in the cool air. The copper stills bubble with steam, and the rosewater flows. The fragrance rises over the desert landscape — ancient, complex, transporting — and the tradition lives on, as it must, if this extraordinary floral heritage is to pass intact to the generations that follow.
