Rose Archiduc Joseph

'Archiduc Joseph' is one of the most richly coloured and historically intriguing of the old Tea roses, combining a vigorous, graceful shrub with unusually complex flowers in copper-pink, coral, rose, muted crimson and occasional mauve tones. Its blooms are very double, usually cupped at first and becoming flatter and more rosette-like as they mature, with petals that twist. It is valued for its long flowering season, attractive grey-green foliage and characteristic Tea rose fragrance. It is particularly successful in warm temperate and Mediterranean climates, where it can flower repeatedly from spring until late autumn and may become considerably larger.

DESCRIPTION OF THE VARIETY

'Archiduc Joseph' belongs horticulturally to the Tea class, not to the modern Hybrid Tea group despite occasional modern catalogues that classify it incorrectly. Tea roses were developed largely in nineteenth-century France from roses of Chinese ancestry associated with the Tea-scented China group. They contributed continuous or recurrent flowering, slender and sometimes nodding flower stems, elegant buds, unusual warm colours and the distinctive fragrance that gave the class its name. Within this group, 'Archiduc Joseph' is remarkable because its ornamental effect depends less on a conventionally perfect flower than on colour, texture and continual transformation. A single bloom may contain salmon, copper, deep pink, rose-purple and warm orange-brown simultaneously. Historical Nabonnand descriptions called the colour a bluish rose with a vivid copper centre and paler petal margins, while the 1900 account in the Journal des Roses emphasized that these colours remained attractive until the flower was completely spent. This capacity for chromatic variation is one of the cultivar's defining qualities: cooler conditions often intensify crimson, brick and purplish tones, while warmer conditions tend to bring forward salmon, peach and copper.

The rose also has substantial historical importance. Gilbert Nabonnand worked on the French Riviera, where the warm climate allowed Tea and China roses to be grown and bred under conditions far more favourable than those prevailing in northern Europe. 'Archiduc Joseph' belongs to the mature phase of nineteenth-century Tea-rose breeding, when the class had developed large, repeatedly flowering shrubs with an extraordinary range of copper, salmon, pink and buff pigmentation. Nabonnand and his sons continued working with Tea roses even as Hybrid Teas became increasingly fashionable, and 'Archiduc Joseph' became one of the family's surviving signature cultivars.

Its continuing garden value is practical as well as historical. It is vigorous without requiring the severe annual pruning normally associated with modern exhibition roses, repeats generously, can be grown as a broad shrub or lightly trained against a support, and has demonstrated surprisingly good health in suitable climates. It therefore works particularly well in informal rose gardens, mixed borders, Mediterranean-style plantings, large containers, warm walls and collections of nineteenth-century roses.

FLOWERING

Rose variety 'Archiduc Joseph' is strongly repeat flowering. In warm climates it behaves almost as a continuous bloomer, with a substantial first display followed by successive cycles through summer and into autumn. The original 1900 description specifically noted abundant flowering and regarded the autumn display as especially profuse. Modern observations from southern Europe, Australia, New Zealand and Japan agree that the cultivar continues producing buds whenever temperatures permit.

The flowering rhythm is more characteristic of an old Tea than of a modern Floribunda. Rather than producing several rigidly synchronized flushes followed by obvious periods of inactivity, an established plant may carry mature flowers, newly opening blooms and developing buds simultaneously. There is nevertheless usually a profuse main spring flush, followed by smaller but frequent flushes. Autumn can be particularly beautiful because lower temperatures favour deeper copper, crimson and violet shading.

In very hot climates the plant may temporarily reduce flower size or flowering intensity during extreme summer heat and resume strongly when temperatures moderate. This is not unusual among old Tea roses and should not be interpreted as failure of remontancy. Adequate soil moisture and a deep organic mulch help maintain growth through hot periods.

Flower bud:

The flower buds have conical shape and are medium to large in size. When the sepals start to divide, a clear carmine colour, becoming paler toward the tip as the petals prepare to unfold. The developing buds may appear coppery, golden or dark rose depending on the season and temperature, which is consistent with the exceptional variability of the opened mature flowers.

The developing flower initially retains a compact Tea-rose form before the numerous petals expand into a deeper cup.

The sepals have medium green colour with lighter yellowish green to the edges, their surface is glandular and the edges are hairsuite grayish-white. There are typically 2 lightly appendaged sepals and 3 sepals with hairy edges. The peduncle is medium green in colour, has smooth surface and is rather strong, appears relatively slender compared with the weight of the full flower, contributing to the relaxed, occasionally nodding presentation characteristic of Tea roses. The receptacle is medium sized, rounded in shape and has smooth medium green colour.

Bloom:

The opened flowers of the rose variety 'Archiduc Joseph' are medium sized, usually around 7 - 8 cm (2.8 - 3.1 in) in diameter under ordinary garden conditions, although historical descriptions called them large or even very large in relation to contemporary Tea roses. The flowers are very full and commonly contain 80 to 90 petals, although petal count is naturally variable according to season and plant vigour.

The young bloom is generally cupped and densely filled with petals. As it opens, the central petals become increasingly irregular, folded and crumpled, creating a loose rosette or quartered effect. Individual petals may curl backward or twist upon themselves. The mature flower can therefore resemble an old garden rose more than the pointed, spiral form generally associated with later Hybrid Teas.

Colour is the outstanding feature of this rose. Buds start with dark rose or carmine. On opening, the dominant shade may be coppery pink, salmon-pink or warm rose, while the interior develops orange-copper, brick, crimson or brownish-orange tones. The margins usually remain distinctly lighter. Under cool or humid conditions, bluish-rose, mauve or violet undertones may become evident; warm dry weather can emphasize coral, peach and salmon instead. The flowers are generally pink with bluish shading, a brown-orange centre and paler margins, very closely corresponding to Nabonnand's historical descriptions.

The flowers may be solitary or produced in small clusters. The display is informal rather than uniformly architectural: the slightly spreading plant carries blooms at different stages among the foliage, giving an established shrub the appearance of a continuously changing tapestry of pink and copper.

Petals:

The petals are numerous, comparatively soft and flexible rather than thick and rigid. Outer petals are broader and form the supporting cup, while smaller inner petals become densely arranged toward the centre. Their margins may curl, fold or appear slightly pointed, and mature flowers frequently acquire the characteristic “crumpled” appearance repeatedly mentioned in French descriptions.

The flower is not static. Young petals may be smooth and relatively orderly, whereas mature ones twist and overlap until the centre becomes an irregular rosette. This evolution is an important part of the cultivar's charm. Historical observers considered the flowers to possess unusually good substance and reported that the colour remained attractive through the life of the bloom and tolerated inclement weather well.

Petal colour also changes with age, but not simply by fading. Copper, coral and bluish-pink may become more conspicuous while peripheral petals pale. The result is often a stronger contrast between the warm interior and lighter outer portion of an older flower. The petals have good self cleaning quality, they last on a plant for 3 to 5 days under normal growing conditions, but in heat they shatter more quickly.

Fragrance:

The fragrance of 'Archiduc Joseph' is moderate and of recognizably Tea character, but its strength varies. Tea rose fragrance is strongly influenced by temperature, humidity, time of day and individual perception, therefore its intensity may vary from light to slightly strong. Its character is generally warm, dry and aromatic, with a distinctive earthy or woodland quality associated with old Tea roses.

Reproductive parts:

Because the flower is very full, stamens and pistils are normally largely concealed until the bloom is fully expanded. The cultivar was nevertheless fertile enough to participate in later breeding. Australian rose records list Alister Clark's ‘Courier’, introduced around 1930, as Rosa gigantea × 'Archiduc Joseph', indicating successful use of ‘'Archiduc Joseph' as a pollen parent.

PLANT

Rose variety 'Archiduc Joseph' is a repeat-flowering Old Garden Rose of the Tea class. Under ordinary temperate cultivation the mature and well-established plants of this rose generally form a bush approximately 120 - 150 cm (4 - 5 ft) tall and around 90 - 120 cm (3 - 4 ft) wide. Warm climates, rich soils and light pruning can produce substantially larger plants; in such conditions the plant forms much larger plants toward 250 cm (8 ft) tall, and plants trained against a support may approach 200 - 300 cm (6.5 - 10 ft) in height.

Its growth habit is broad, branched and somewhat spreading: the plant can be formed as a large shrub, but its flexible elongated shoots also lend themselves to informal training on a low trellis, pillar or warm wall. It should not, however, be regarded botanically or horticulturally as a true Large-Flowered Climber. It is best suited to warm, sheltered gardens but can be successfully grown in colder temperate regions where careful siting and winter protection compensate for the Tea class's inherent tenderness.

It is best given a position in full sun in temperate climates, with a warm protected place. In very hot continental or Mediterranean gardens, some shade will provide a relief from the fiercest afternoon sun and can preserve flower quality. The soil should be reasonably fertile, humus-rich and well drained while remaining evenly moist during active growth. Some gardeners report an ability to tolerate relatively poor soil, but this should not be interpreted as a preference for impoverished conditions.

Tea roses resent the hard annual pruning commonly given to modern Hybrid Teas. Preserve the permanent framework, remove dead, diseased, crossing or very weak wood, and shorten vigorous shoots only enough to maintain shape. Old exhausted canes can gradually be replaced from the base. In colder climates, pruning is safest after the danger of severe frost has passed, because late-season or premature pruning can stimulate tender growth.

For container growing, use a generous pot rather than attempting to maintain the cultivar indefinitely in a small container. Its naturally broad root system and vigorous top growth require substantial soil volume and regular irrigation.

Foliage:

There is a normal quantity of the foliage on the plants of rose 'Archiduc Joseph' and it is one of its distinct features, especially compared with many modern rose hybrids. The foliage is an unusual ash-grey-green and medium sized, giving the shrub an individual appearance, it may range in colour from matt grey-green to darker, only slightly glossy green, depending on climate and growing conditions. Leaves provide a restrained background to the unusually warm flowers. In healthy plants the foliage can be sufficiently dense to give the shrub ornamental value even between flowering peaks. New growth may acquire bronze, copper-red or burgundy coloration before becoming green.

Leaflets:

The normal leaves in the middle of the flowering stem typically have five leaflets, including the terminal leaflet, with additional leaflets possible on vigorous vegetative growth, and sometimes three leaflets occur closer to the flowering cluster. The dark grey-green leaflets have an ovate to elliptic shape, generally with an acute or pointed apex and serrated margins, the type of serration is single and small; the appearance of the leaflets is relatively narrow, matt and rough. As with many Tea roses, foliage appearance is comparatively refined. The petiole and rachis are relatively slender and support the leaflets in an open pinnate arrangement.

Wood:

The wood provides one of the clearest historical diagnostic characters. The Journal des Roses described the canes as relatively substantial and reddish brown, which may seem reddish-copper in colour. The canes of rose 'Archiduc Joseph' are smooth and flexible, sometimes developing wire-like branches. Young shoots can be slender, but mature basal canes gain considerably in diameter. Branching is free, resulting in a rounded or spreading shrub. The weight of the flowers can bend younger laterals outward, producing the relaxed, arching form prized in old Tea roses. When allowed to retain long canes, the plant can be tied horizontally or diagonally to a support, stimulating flowering laterals and producing the effect of a small climber.

Prickles:

THe rose variety 'Archiduc Joseph' has very few prickles on the main canes and on the laterals from the main canes under normal growing conditions. The prickles are strong and hooked downward in shape, and have reddish-brown colour when young maturing to brown colour. For a plant corresponding closely to the historical Nabonnand description, substantial recurved prickles should therefore not be considered anomalous. Gloves are still advisable during pruning and training, particularly when working with older woody canes.

Small prickles:

Under normal growing conditions the small prickles are not observed on the main canes and on the laterals from the main canes, as well as on the flowering canes or peduncles. Minor prickles may occur on young leaf rachises, as in many Tea roses, but their quantity is small.

Disease resistance and stress tolerance:

'Archiduc Joseph' appears to be unusually healthy for a nineteenth-century rose when grown in a climate suited to Tea roses. The strongest modern evidence comes from Auckland Botanic Gardens, where roses were evaluated under a no-chemical-spray programme. In the 2020–2021 assessment 'Archiduc Joseph' received a rating of 9 out of 10, placing it among the garden's “Star Performers”; no significant pest or disease incidence was recorded beside the cultivar in the published table. Particularly interestingly, its seed parent ‘Madame Lombard’ received a lower rating of 6 and was recorded with 50% black spot in late January. ^[1] This supports the repeated horticultural reputation of 'Archiduc Joseph' as a reasonably healthy Tea rose, but it should not be converted into an absolute claim of immunity. Black spot and powdery mildew remain possible where summers are cool, humid or poorly ventilated. Rust is less often specifically associated with this rose, but resistance or immunity to rust has been proven up to this date.

Its tolerance of heat is well documented: rose that originated in the French Mediterranean region and performs strongly in southern France, Italy, Australia, New Zealand and other warm-temperate environments. Once established it can tolerate considerable summer heat, although prolonged drought can reduce flower size and repeat performance. Deep mulch and occasional thorough irrigation are preferable to frequent shallow watering.

Cold hardiness requires greater caution. This rose is not winter hardy, ad is recommended for growing in climates similar to USDA Zone 7 and warmer, commonly recommended for USDA zones 7 - 9 with sheltered situations. In cold temperate gardens, plant against a south- or west-facing wall, avoid frost pockets and exposed winter winds, mulch deeply over the root zone and mound composted material around the crown before severe winter weather. Where temperatures regularly fall below approximately −15 °C (5 °F), growing in a large movable container or providing substantial winter protection is safer than relying on unprotected garden survival.

The name of this rose commemorates Archduke Joseph Karl of Austria, Joseph Karl Ludwig of Habsburg-Lorraine (1833–1905), a member of the Hungarian branch of the Habsburg dynasty. Contemporary and later rose literature portrays him as horticulturally and botanically interested, and modern rosarian accounts identify him as an enthusiastic plant or rose collector.

The French form 'Archiduc Joseph' literally means “Archduke Joseph”. In English-language commerce it has consequently appeared as ‘Archduke Joseph’, although the historically established cultivar name 'Archiduc Joseph' should be retained in formal horticultural usage.

The choice of an aristocratic dedication was entirely characteristic of nineteenth-century European rose culture. Breeders and nurseries frequently named new cultivars after royalty, military figures, patrons, horticulturists and fashionable public personalities. Nabonnand's Riviera nursery catered to an international clientele that included members of Europe's social and royal elite, making such a dedication culturally natural within its original commercial context.

'Archiduc Joseph' has not received any major formal twentieth- or twenty-first-century rose awards such as ADR certification, the RHS Award of Garden Merit, All-America Rose Selections recognition, a World Rose Hall of Fame designation or an award from the Australian National Rose Trial Garden. It predates most of these systems by many decades, and no period competition medal attributable specifically to this cultivar was confirmed.

ORIGIN OF THE VARIETY

Rose variety 'Archiduc Joseph' originated by Gilbert Nabonnand of Golfe-Juan, France. The cultivar is recorded as a Tea rose raised from seed of 'Madame Lambard' (Tea introduced by François Lacharme in 1878). Thus 'Madame Lambard' (more commonly standardized today as 'Madame Lombard') is the documented seed or female parent, the pollen parent was not recorded and is regarded as unknown.

The date deserves clarification because rose literature contains extraordinary inconsistency on this point. Modern catalogues variously print 1872, 1878, 1892 and occasionally 1894. The Nabonnand historical research collection records both 1892 and 1894 in period catalogues but cites the Journal des Roses as stating explicitly that the cultivar was placed in commerce on 1 November 1892. The great L'Haÿ rose collection also listed 'Archiduc Joseph' as Nabonnand, 1892 by 1902. Taken together, these sources make 1892 the most defensible introduction date.

BACKGROUND OF THE VARIETY

Tea roses occupy a pivotal position in rose history. Their Chinese-derived ancestry introduced continuous flowering, warm yellow, apricot, salmon and copper coloration, elegant pointed buds and a distinctive aromatic fragrance into European breeding. 'Archiduc Joseph' appeared late in the great age of the Tea rose, only a few decades before Hybrid Teas largely displaced the class commercially. It therefore represents an advanced old Tea: vigorous, repeatedly flowering, richly coloured and sufficiently substantial to survive in cultivation long after hundreds of its contemporaries disappeared.

Its history is complicated by nomenclatural confusion. It has frequently been associated or confused with Alexandre Bernaix's 1891 Tea 'Monsieur Tillier'. In parts of Australia, New Zealand and the United States, plants circulated under one name while apparently corresponding to plants bearing the other in Europe. A separate complication involved a climbing rose once sold as 'Monsieur Tillier' by Peter Beales; later work identified that particular plant as the climbing Hybrid Tea ‘Marie Nabonnand’. The safest approach for collectors is therefore to judge old plants not merely by flower colour but by provenance, growth habit, foliage and prickles, and where possible to acquire material from collections maintaining verified Nabonnand accessions.

SUMMARY OF THE VARIETY

'Archiduc Joseph' is an exceptional late nineteenth-century Tea rose whose survival is justified by more than historical sentiment. It combines a long flowering season, considerable vigour, attractive grey-green foliage, useful disease tolerance in suitable climates and flowers of remarkable chromatic complexity. Its coppery pink, coral, crimson and mauve shades intensify or soften with season and weather, while the densely folded rosette form gives each mature flower the informality characteristic of the finest old Teas. Rose variety 'Archiduc Joseph' incorporated the following unique combination of characteristics:

  very full flowers combining copper-pink, coral, crimson, salmon and occasional mauve shading;

  strong recurrent flowering, frequently continuing from spring until late autumn in warm climates;

  distinctive grey- to ash-green foliage and reddish-brown wood;

  vigorous spreading Tea rose habit suitable either as a large shrub or for light training on a support;

  good practical garden health under favourable warm-temperate conditions, demonstrated by strong performance in no-spray evaluation.

Rose 'Archiduc Joseph' can be successfully propagated by softwood or semi-ripe cuttings during active growth, by hardwood cuttings in suitable climates, or by chip budding onto an appropriate rose rootstock. Own-root propagation is particularly attractive for preservation collections because new basal growth remains true to the cultivar even if winter injury kills the upper framework. Budded plants may establish more rapidly or perform better in soils where a locally adapted rootstock offers advantages.

COMPARISON WITH PARENTS

The documented seed parent is 'Madame Lambard', generally treated in modern authoritative catalogues as 'Madame Lombard', a François Lacharme Tea rose introduced in 1878. 'Madame Lombard' is itself vigorous and spreading, generally about 100 - 120 cm tall, with dark green foliage and very double salmon-pink flowers opening from long, pointed crimson buds. Its flowering is almost continuous through summer and autumn. 'Archiduc Joseph', however, develops a much more complex and recognizably coppered palette. Instead of the predominantly salmon-pink of 'Madame Lombard', its flowers commonly incorporate copper, orange, coral, bluish pink, brick and mauve, with much paler petal margins. Its mature flowers also become more intricately crumpled and rosette. The foliage offers another contrast: 'Madame Lombard' is usually dark green, whereas 'Archiduc Joseph' has a distinctive ash-grey-green foliage.

The pollen parent of 'Archiduc Joseph' is unknown, so a complete comparison cannot be made.

COMPARISON WITH THE CLOSEST COMMERCIALLY AVAILABLE CULTIVAR

The most meaningful comparison can be made with the Tea rose 'Monsieur Tillier', bred by Alexandre Bernaix and introduced in France in 1891. The comparison must be made cautiously because the two names have been confused in international commerce for many decades, and some plants now sold under either name may represent the same historic clone or incorrectly labelled material.

Historically 'Monsieur Tillier' bears very free-flowering, loosely double flowers of deep rose-pink shaded orange, with purplish-red outer petals. The old L'Haÿ collection summarized its colour as carmine and brick. Its flowers tend toward a somewhat looser, less densely packed structure than the full petalled 'Archiduc Joseph', and the genuine Bernaix cultivar is generally described as a lax, vigorous shrub. 'Archiduc Joseph', by contrast, is large and full, initially cupped, with bluish-pink, a vivid copper centre and paler margins. Its inner petals become conspicuously entangled, folded and crumpled. The grey-ash foliage and strong hooked prickles recorded in the 1900 description are useful identification characters and differ from larger dark green, more glossy and larger leaves of 'Monsieur Tillier'.
