Rose Rose à parfum de l’Haÿ

Among the early Hybrid Rugosas, few roses unite fragrance, stamina, and historic interest more memorably than "Rose à parfum de l’Haÿ". It carries large old-style blooms in dark cherry-carmine to crimson-purple tones, and it does so on a shrub far hardier and more weather-tolerant than many roses of comparable perfume. It satisfies the collector who values lineage and rose history, and it serves the practical gardener who needs a robust, deeply scented shrub for real garden conditions. Even now, more than a century after its introduction, it remains one of the most persuasive arguments for the enduring value of the Hybrid Rugosa class.

DESCRIPTION OF THE VARIETY

Rose à parfum de l’Haÿ is best understood as a Hybrid Rugosa, even though it is still sometimes offered under botanical-style forms such as Rosa rugosa "Rose à parfum de l’Haÿ". That older naming reflects the plant’s obvious rugosa inheritance - stout prickly wood, textured foliage, and notable winter hardiness - but the cultivar is not a simple rugosa selection. Its documented parentage combines an intermediate Damask–Hybrid Perpetual seedling with rugosa blood, and this mixed origin explains why its flowers feel more opulent, darker, and have more in common with Old garden roses than those of the species itself. The plant of this rose grows with the practical force of rugosa breeding, while the bloom carries the richer floral charm of old perfume roses and nineteenth-century red roses.

This was a rose created in the context of serious fragrance work, and the old description printed at L’Haÿ emphasized not only beauty and remontancy, but perfume of unusually fine quality. In modern gardens that purpose still reads clearly. The Rose à parfum de l’Haÿ is not chiefly a rose for hips, nor for clipped formality, nor for the continuous machine-like flowering expected of recent landscape shrubs. The value of Rose à parfum de l’Haÿ lies in the combination of a strong first flower display, a later repeat flowering of variable strength, and a fragrance that gives the whole plant an almost ceremonial quality in the garden. Because it emerged in the same milieu and period as "Roseraie de l’Haÿ", the two are still occasionally confused in literature and trade; yet "Rose à parfum de l’Haÿ" is generally the more globular-flowered and more overtly Old-rose scented of the pair, and it retains a distinct identity of its own.

FLOWERING

Flower bud:

The flower buds are large and rounded, almost spherical before opening, borne on reddish peduncles that are about 3 - 5 cm (1.2 - 2 in.) long and have a hairy and glandular surface. The calyx is long-turbinate in the ovarian part, with sepals reflexing at anthesis. The sepals are triangular, entire, and setaceous-tipped, green outside, slightly hispid, and silky with a pinkish cast within. Generally the buds have a full, old-rose character from the start, opening more by gradual swelling and loosening.

Bloom:

The open flowers of this rose are large, usually about 8 - 10 cm (3.1 - 4 in.) in diameter, though size varies with season and cultivation. They start to open as distinctly globular, then broaden and flatten with age, so that the plant can show both rounded and almost saucered blooms at once. The colour is best described as cherry-carmine to deep crimson-red, often with purplish or lilac shading, the margin of the petals is slightly lighter and they have a pale or whitish basal spot at the base of the petals. Flowers are produced singly or in small corymbose clusters, and the main flush is profuse enough to make the shrub appear a dark, scented gobelin. Repeat flowering can be expected later in the season, but it may be not as profuse, in some climates rather occasional, scattered, but sufficiently recurrent to separate it from strictly once-blooming old Shrub roses.

Petals:

The flowers of "Rose à parfum de l’Haÿ" are double, with the number of petals ranging from 17 to about 40. The petals have obcordate, notched or subtly mucronate shape, and the central petals tend to curl and recurve, creating a looser, somewhat crimped fullness in the center. Their texture appears moderate rather than thick: enough to give good bloom presence, but not the thick, rain-armored texture of some later shrub roses. As the flower ages, the globular form relaxes, the center opens, and the color may fade slightly toward violet or muted purplish tones. This change of form with maturity is part of the rose’s charm, giving the shrub a sequence of floral expressions rather than one fixed exhibition stage.

Fragrance:

Fragrance is the central fact of this rose. The original L’Haÿ description called it a perfume of exquisite sweetness, recalling a mingling of the scent of Damask roses and Général Jacqueminot, and later descriptions continue to place it firmly among the strongly scented roses. Modern evaluations describe its scent as fruity, myrrh-like, sharply spicy; it belongs to the Old rose family of fragrance - rich, warm, and unmistakably floral, with a damask depth that justifies the name. In favorable weather the scent carries well into the surrounding air, which is one reason the variety is so satisfying near a sitting place, doorway, or path edge - provided the plant is sited so that its formidable armature does not become a nuisance. As with many fragrant roses, strength is likely to vary with temperature, air movement, and the age of the bloom.

Reproductive parts:

"Rose à parfum de l’Haÿ" has white, incurved stamen filaments with dark yellow anthers, very short styles, and pale yellow, projecting stigmas. The reproductive structures are less visually dominant than in the simpler Hybrid Rugosas, because the flower is fuller and often partially obscures them until the bloom broadens with age. This rose almost does not set the fruits (hips), the variety produces no hips or only very scant ones. That relative sterility accords well with its listing as triploid, and it means the rose is grown for bloom, scent, and shrub character rather than for autumn fruit display.

PLANT

Classified as a Hybrid Rugosa shrub, "Rose à parfum de l’Haÿ" typically forms an upright, bushy, densely armed plant. The mature and well-established plants of this rose typically reach the height of about 120 - 150 cm (4 - 5 ft) and grow about the same in width, though in favourable climates with good care long-grown specimens report larger dimensions, exceeding 150 cm and growing almost 200 cm (ft6.5 ) tall. The general character of the plants is erect, slightly bending when mature, substantial, thickly furnished with prickles, and capable of making a dense garden presence rather than a loose, arching old-rose fountain. It is therefore best regarded as a medium-to-large shrub for mixed borders, informal hedging, or specimen planting where strong scent and strong armature can both be appreciated.

In cultivation this rose benefits from the broad constitutional virtues associated with rugosa breeding: tolerance of exposure, a willingness to grow in less-than-ideal soils, and an ability to cope with cold that would discourage many highly perfumed Old roses. Full sun remains the best position for flower quality and repeat, and a site with good air movement is prudent where summer humidity is high. It should not be over-indulged; like many rugosa hybrids it is often best suited for simple garden soil than in excessively rich, heavily fertilized mixes. Pruning is best conservative. Late winter or very early spring is the appropriate time to remove dead, damaged, or congested growth and, where necessary, to renew the plant gradually by cutting out a portion of the oldest canes close to the base. Hard annual shortening is seldom necessary unless a neglected plant is being rejuvenated. In use it suits cottage and informal gardens, mixed shrub borders, rougher outer garden compartments, and defensive or screening plantings, but it is less suitable where people must brush closely past the canes.

Foliage:

The foliage is one of the reasons this cultivar remains ornamental even outside peak bloom. It is dark green, substantial, and attractive, with surface dark and matte, and visibly wrinkled. The leaves are thick and well furnished, with strong venation and clear rugosa influence, but sometimes less coarsely puckered in effect than the species or the roughest of its hybrids. That makes the foliage attractive without becoming coarse. In mass it gives the shrub a dense, upholstered look, and gardeners value it precisely because the dark leaf surface makes the carmine flowers seem even richer.

Leaflets:

The number of leaflets on normal mid-stem leaves is typically 7 with variations from 5 to 9, including the terminal leaflet. These leaflets are oval-acute, finely serrated, nearly sessile, glabrous, somewhat glaucescent beneath when younger, and dark green above when mature, with strong reticulate venation and a slightly bullate surface which slightly differs from Rugosa ancestry. The stipules are elongated and broad with acute divergent auricles, and the petiole is pinkish toward the base, tomentose-glandular, and armed with retrorse prickles. This is excellent evidence of why the cultivar reads unmistakably as a Rugosa derivative even while its flowers depart from the plainness of the species. The overall effect of the leaflet is of robust, well-spaced, of moderate to fairly large size.

Wood:

The plants of the "Rose à parfum de l’Haÿ" have robust, upright, thorn-laden canes and tend toward a compact thicket rather than lax sprawling character. Old wood is very prickly, while young shoots are green and vividly armed, helping to create the dense, defensive architecture so often prized in rugosa hedges. The plant of this rose is bushy, upright, and vigorous and does not rely on elegant arching stems for its effect; its architecture is more structural and self-supporting, which makes it useful in rougher or windier settings. When mature, the plant usually carries enough branching from the base to look full without extensive formative pruning.

Prickles:

The mature canes of this rose are well armed with straight, grey prickles, while young growth bears spreading, flattened, broadly based, decurved prickles that are pinkish in tone. The size of the prickles varies very much, and this mixture of large, unequal armature is thoroughly in keeping with the rugosa side of the pedigree. They make the shrub excellent for barriers and secure hedging, but ill-suited to close hand-weeding by an unprotected bare arm. The plant should be given enough room that its perfume can be enjoyed without constant conflict with its prickles.

Small prickles:

The main canes and the laterals from the main canes have large quantity of small prickles, petioles and young growth carry smaller retrorse prickles in addition to the larger. This contributes to the dense, almost protective character typical of many rugosa-derived shrubs.

Disease resistance:

The "Rose à parfum de l’Haÿ" is far more practical garden plant than many old highly scented roses of Damask or Hybrid Perpetual character as it is constitutionally tolerant of cold, and it is considered hardy enough for severe climates. The plants of this rose are generally robust and disease resistant, and drought tolerant, but they are not immune. "Rose à parfum de l’Haÿ" is usually healthier than delicate old garden classes, especially in cool, open, temperate conditions, but is susceptible to black spot and powdery mildew where summers are hot, stagnant, or persistently humid. The resistance to rose rust is accessible.

Winter hardiness is excellent and commonly listed as USDA zone 2b or warmer, and Royal Horticultural Society does not show a public RHS H hardiness code for this cultivar. In heat, the rose appears capable of growing beyond strictly cool climates, but its finest foliage, bloom substance, and overall poise generally benefit from cooler climates rather than from oppressive summer heat.

The name is rooted in both purpose and place. In French, “rose à parfum” signifies a perfume rose, or a rose intended for fragrance use, and “de l’Haÿ” links the cultivar to the rosarium at L'Haÿ-les-Roses, now known as Roseraie du Val-de-Marne.

Over time, catalogues and databases shortened or altered it to “Parfum de l’Haÿ”, "Rose à parfum de l’Haÿ", or even “A Parfum de l’Haÿ”; the Royal Horticultural Society accepts also names "Rose à parfum de l’Haÿ" and lists Rosa ‘A Parfum de l’Haÿ’ as a synonym, while other long-used rose records preserve the form Rose à Parfum de l’Hay without the diaeresis.

The botanical-style synonym Rosa rugosa "Rose à parfum de l’Haÿ" reflects older horticultural custom and the strong rugosa appearance of the plant, but the rose itself is a Hybrid Rugosa rather than a pure Rugosa form.

ORIGIN OF THE VARIETY

Rose à parfum de l’Haÿ was bred in France by Jules Gravereaux. A careful suggestion is that the crossing began in 1894, first flowering in 1900, followed by naming and early release in 1901, and further trade distribution by Charles Pierre Marie Cochet-Cochet in 1903. The breeding sequence began in 1894 with the fertilization of a Damask rose by Général Jacqueminot; that resulting plant was then crossed again with Rosa rugosa, and the final seedling first flowered at L’Haÿ in 1900.

Rose variety "Rose à parfum de l’Haÿ" originated by crossing the seed parent - unnamed rose seedling, which was a result of cross pollination of the Damask rose ‘Summer Damask’ with the Hybrid Perpetual ‘Général Jacqueminot’, which was then fertilized by the pollen parent Rose rugosa.

BACKGROUND OF THE VARIETY

"Rose à parfum de l’Haÿ" occupies an unusually meaningful place within the Rugosa hybrids because it was tied not only to ornamental improvement but also to perfume experimentation. Gravereaux’s work in fragrance roses sought a rose with rich scent, repeat flowering, and practical garden constitution, qualities useful in theory for the perfume industry. That industrial ambition was never truly realized on a commercial scale, but the breeding program left behind a cultivar of exceptional horticultural afterlife. Rose à parfum de l’Haÿ therefore stands beside such historic Hybrid Rugosas as 'Blanc Double de Coubert', 'Conrad F. Meyer', 'Mme Georges Bruant', and the closely related ‘Roseraie de l’Haÿ’, yet it remains distinctive for the old-rose depth of its perfume and the darker opulence of its bloom. It is one of the rare roses whose historical purpose still enriches its garden meaning.

SUMMARY OF THE VARIETY

"Rose à parfum de l’Haÿ" remains one of the most prominent fragrant Shrub roses for gardeners who value both history and resilience. It is not a perfect rose in the modern glossy-landscape sense: its repeat can vary, its health is not absolutely immune in every climate, and the plants are very prickly. But this rose also offers an amazing depth of scent, Old rose character, and wonderful enduring shape of the bush. In cold and temperate gardens especially, it remains an admirable choice for informal hedges, mixed shrub plantings, heritage collections, and any place where fragrance should be experienced as part of the architecture of the garden. This rose variety incorporated the following unique combination of characteristics:

  large, dark cherry-carmine to crimson-purple double flowers which globular at first and flatter with age;

  an Old rose fragrance of unusual strength, historically prized as a true perfume quality rather than a merely sweet scent;

  bushy, upright, heavily armed shrub constitution with clear Rugosa toughness and strong winter hardiness;

  dark, textured, ornamental foliage that supports the flower color and strengthens the shrub’s landscape value even out of bloom.

The methods suitable for the rose cultivar "Rose à parfum de l’Haÿ" include propagation by cuttings and by budding; for specialist production, own-root plants are also entirely suitable where true stock is maintained.

COMPARISON WITH PARENTS

Compared with the pollen parent, Rosa rugosa, the cultivar departs markedly from the species in floral form and garden expression. It has much fuller, darker, more refined blooms, a stronger Old rose fragrance, and a much reduced emphasis on hips. Yet it retains what matters most from the rugosa side: thickly textured foliage, conspicuous prickles, toughness in exposed or poor sites, and very high winter resilience.

COMPARISON WITH THE CLOSEST COMMERCIALLY AVAILABLE CULTIVAR

The most meaningful comparison in present commerce is with "Roseraie de l’Haÿ", another dark red Hybrid Rugosa from the same historical circle and a rose with which this cultivar is still sometimes confused. "Roseraie de l’Haÿ" is generally the larger and more expansive shrub, commonly reaching around 180 cm (about 6 ft), with large purplish-crimson semi-double blooms to about 11 cm (4.3 in.) in diameter, opening almost flat and showing cream stamens clearly. In contrast "Rose à parfum de l’Haÿ" is usually somewhat smaller and denser, more often placed around 120 - 150 cm (4 - 5 ft), and its blooms tend to begin more globular and feel more very double and Old-fashioned in character, even when they later flatten. Colour in "Rose à parfum de l’Haÿ" usually leans more cherry-carmine with violet undertones, whereas "Roseraie de l’Haÿ" is often described as purplish-crimson or crimson-purple.

In the garden, "Roseraie de l’Haÿ" appears as the bolder hedge or background shrub: bigger, flatter-flowered, and more obviously landscape-structural. "Rose à parfum de l’Haÿ", by contrast, is the more intimate and more antique-flowered plant, its chief glory being the union of dark double bloom and historically celebrated perfume. If the gardener wants a larger, more openly semi-double Rugosa effect with strong repeat flowering, "Roseraie de l’Haÿ" is often the better choice. If the priority is a richer Old rose flower form and a more richly perfumed rose "Rose à parfum de l’Haÿ" is the more preferable choice.
