Rose Ali Dorate

'Ali Dorate' is a modern Floribunda rose introduced by Italian breeder Enrico Barni that is covered in clusters of semi-double blooms in a clear lemon-yellow, offering a bright, sunny display in the garden. The flowers are held on an upright, bushy shrub cloaked in glossy dark green foliage. This variety is prized for its abundant, season-long blooming: literally covering the plant in cheerful, “butterfly-like” yellow flowers for months on end. The blooms are set on sturdy, well-branched stems that make it a striking choice for borders or mass plantings.

DESCRIPTION OF THE VARIETY

'Ali Dorate' like its Floribunda kin blooms in clusters and repeats throughout the season. What makes 'Ali Dorate' distinctive is its vivid lemon-yellow color and prolific flowering habit. It produces a large mass of yellow flowers that suffuse the plant with color. The overall floral effect is a shimmering yellow tapestry – especially effective in sunlit borders or butterfly gardens. The foliage is unusually lustrous: each leaf is deeply green and glossy, reputedly with a shape sometimes likened to a beech leaf. This healthy, disease-resistant foliage sets off the bright blooms. 'Ali Dorate' remains relevant today for its combination of intense color, strong repeat-flowering, and ease of culture, making it a reliable yellow bedding rose or specimen shrub for temperate gardens.

FLOWERING

'Ali Dorate' is an abundant, recurrent bloomer. Plants flush repeatedly from late spring until frost, often producing several abundant flushes of blooms. In each cycle, many buds open at once so that the shrub becomes literally covered with flowers. The result is a dramatic and sustained display of lemon-yellow blossoms for most of the season. Its floriferousness makes it especially attractive planted in masse or near walkways where the massed golden blooms can be fully appreciated.

Flower bud:

The flower buds are moderately sized and have very elongated in shape, they are quite narrow and long with sepals exceeding significantly the leng of the bud itself. The sepals are long, lanceolate, medium green to dark green in colour with strong brown-red anthocyanin on the edge and in the central part of the sepals. There are 3 normally appendaged sepals and 2 unappendaged sepals with hairy margins. The receptacle is small, medium green in colour rounded and has a rather smooth surface. The peduncle in long, strong and stiff, has medium green colour with strong brown-red anthocyanin and densely covered with reddish glandular hairs and small prickles. As the buds start to open the golden-yellow of the petals shows at the tips. Buds typically open evenly rather than in stages, so that all many flowers on a branch within a cluster open around the same time.

Bloom:

Each bloom of the rose variety 'Ali Dorate' is typically medium-sized, about 8 - 9 cm (3.5 inches) in diameter and has flat form when fully open. The flower is semi-double, with roughly 9 - 16 petals per bloom. When fully open the bloom presents a broad, flat rosette of petals. The petals overlap in loose layers, not tightly packed, giving the flower an open, free and wild look. The color is a clear lemon-yellow to golden-yellow. Young blooms may be quite vivid, but they tend to fade as they age or if exposed to strong sun. The petals often bleach to a cream or pale yellow by the end of the bloom’s life. The petals have only minor ruffling at the edges; most blooms stay fairly flat until the end. They appear in medium sized clusters of five to fifteen flowers, the overall effect is a swath of cheerful yellow that stands out even from a distance.

Petals:

The petals are broadly oval with a smooth and rather thick texture. They feel moderately heavy and have a silken sheen. The margins are gently curved but not highly undulating. Petal durability is fair: blooms usually hold their form on the bush for about 5 to 8 days, depending on weather, and the petals drop off cleanly after flowering, keeping the plant neat and tidy. The lemon-yellow color can fade to pale cream with age or sun exposure and at the end of a flush, old blooms may turn almost white before shedding, but this has not caused any discoloration on the new petals. Sometimes the petals may show a light pink tint towards the edges. The petals structure is relatively firm, so that rain or brief drought have only a mild effect on them; however, heavy rain can still knock flowers about, as with most open roses.

Fragrance:

The fragrance of 'Ali Dorate' is very light to negligible, and its faint hint of sweetness is easily overwhelmed in a flower border. The center of the flower, with its prominent stamens, allows easy air circulation but does not produce a strong perfume.

Reproductive parts:

With the semi-double form, a prominent boss of golden-yellow stamens are exposed when the bloom opens. The stamens are conspicuous and long-lasting, remaining bright even as the petals fade. The pistil structures are pale and not especially showy.

PLANT

The rose variety 'Ali Dorate' is classed firmly as Floribunda rose - a modern garden shrub class created by crossing Polyantha and Hybrid Tea lines. It is a bushy, upright shrub in habit. When mature, plants form a somewhat compact mound of upright, arching canes. The main canes are usually stiff, setting the overall shape; secondary branching produces many flowering laterals. Under good conditions the plant develops strong growth and it is erect enough that staking is seldom needed except in very exposed sites.’Ali Dorate' grows best in full sun, where it can achieve its typical 70 - 90 cm (2.3 - 3 ft)height and about 50 - 60 cm (1.6 - 2 ft) in width. In rich soil and warm climates it may grow taller and more open, reaching about 100 - 120 cm (3.3 - 4 ft) in height while remaining well-formed. The balance of bloom and foliage is good: on average the plant bears many flowers but still maintains a healthy canopy of leaves.

Like most Floribundas, 'Ali Dorate' is adaptable and easy to grow. It thrives in moderately fertile, well-drained soil and tolerates a range of conditions, from southern Europe up to USDA zone 6 (-23°C) climates. Good air circulation around the canes is advisable to keep the healthy leaves dry. Standard rose care is advised: prune in early spring to shape the shrub and remove weak wood, and cut back old canes to encourage renewal. A light summer pruning to remove faded blooms will prompt fresh flushes. Mulching and adequate moisture enhance flowering, but the plant also shows respectable drought tolerance once established. After flowering, any slender or crossing stems can be thinned to maintain form. Since the blooms are set on the upper portions of stems, it is best used in a middle or background position in the border, rather than as an immediate front-of-border rose.

Foliage:

On the plants of the rose variety 'Ali Dorate' the foliage is dense and abundant. The leaves are glossy dark green, providing an attractive backdrop to the yellow blooms. Each leaf is usually compound, with typically 5 leaflets on the normal leaves in the middle of the flowering stems, including the terminal leaflet. The new foliage and growth appears brown red maturing later to dark green. One distinctive feature of this rose is its unusually “wide” or beech-like outline of the leaves. The foliage remains attractive throughout the season, it rarely suffers from nutrient chlorosis or scorch in typical garden conditions. Because of its vigor and health, the leaves are quick to re-foliate after winter dieback. This results in plants that stay clean from the diseases most of the season in mild climates, and tend to recover well after rare infections. The overall leaf growth is generous: the canopies tend to fill in well, maintaining a full habit.

Leaflets:

As in most modern roses, smooth in texture, with a somewhat elongated oval shape and a pointed tip. The edges of the leaflets are distinctly serrated, the type of serration is very large and single, which contributes largely to its beech-like appearance with a darker reddish margin even on mature leaflets. The petiole and central rachis are relatively smooth with no unusual glandular structures. Leaflet veins are prominent and parallel, giving a well-defined venation pattern against the glossy surface.

Wood:

The canes of 'Ali Dorate' are medium-thick and firm. New shoots emerge green strongly suffused with red but soon wood over to a pale green brown. Branching is fairly dense: from each main cane, numerous lateral shoots develop the flowering stems. The overall plant shape tends to be upright rather than sprawled. Wood is reasonably vigorous, which contributes to the plant’s hardiness. The wood shows no special brittleness or weakness; however, in regions with heavy rains or strong wind, tall flushes of flowers can weigh on the canes, causing occasional bending or breakage. For best appearance the canes with spent flowers can be pruned back more radically to keep the plant balanced.

Prickles:

'Ali Dorate' carries a typical armament for a modern Floribunda: relatively few, slender prickles on the canes. These prickles are usually small, straight or slightly curved, and not densely packed. On new shoots they may appear reddish-brown, maturing to a grayish tone on older wood. Because the canes can become woody, pruning gloves are still recommended, but this rose does not present unusual armature.

Small prickles:

Under normal growing conditions the small prickles are not observed on the main canes and on the laterals from the main canes of this rose. By all accounts, the woody stems of 'Ali Dorate' simply bear the standard prickles noted above, with no additional micropapillae or clubs of note.

Disease resistance and stress tolerance:

'Ali Dorate' is widely reported to have strong disease resistance for a yellow rose. In trial comments and growers notes, it is consistently described as very disease resistant , especially to both black spot and powdery mildew and its foliage is very healthy and one of the best among yellow roses. Under normal growing conditions, the leaves stay largely free of unsightly spots; occasional mildew outbreaks are rare and usually minor. Rust is uncommon on this variety. The combination of glossy foliage and reflexed petal form (which sheds water easily) helps it avoid prolonged wetness, further aiding disease resistance. In hot and humid climates, it may still require standard preventive care, but even then it performs better than many double yellow roses.

In terms of cold hardiness, rose 'Ali Dorate' is recommended for growing in climates similar to USDA Zone 6 to 10 (surviving -23°C) and is generally fairly winter-hardy in moderate European climates. It also shows good heat tolerance, it remains heat-resistant without burning its foliage, established plants will tolerate short droughts better than many Hybrid Teas.

The name “Ali Dorate” is Italian for “golden wings”, likely chosen to evoke the shape and color of the flowers and to fit the Barni breeder’s theme of butterflies (as in the series name “Le Farfalle”). It is reminiscent of the Italian phrase “sull’'Ali Dorate'” (on golden wings) from Verdi’s famous chorus, suggesting a poetic “butterfly” image.

This cultivar earned recognition in European new-rose trials in 2010. It won the Silver Medal at the International New Rose Competition of Le Roeulx (Belgium, 2010). In the same year it was awarded a Certificate for Floribundas at the Bagatelle Trials (Paris, 2010). No other major awards (e.g. AARS, ADR, etc.) are recorded for 'Ali Dorate’ to this date.

ORIGIN OF THE VARIETY

‘BARaldo’ / 'Ali Dorate' was bred by Enrico Barni of the Rose Barni nursery in Italy. Precise seed parent and pollen parent are not officially published and seems to have been kept proprietary.

BACKGROUND OF THE VARIETY

Barni’s 'Ali Dorate' is part of Floribunda roses' long lineage, representing a modern breed of Floribunda optimized for color and health. It belongs to Barni’s “Le Farfalle” (Butterflies) series of floribundas, which comprises other mostly yellow or pale cultivars designed to attract pollinators.

SUMMARY OF THE VARIETY

'Ali Dorate' is a modern Italian Floribunda rose valued for its glowing lemon-yellow blooms and vigorous repeat flowering. It combines vivid flower color with easy maintenance and health, making it a standout in a sunny garden setting and this rose variety incorporated the following unique combination of characteristics:

  brilliant lemon-yellow semi-double flowers gathered in clusters make a strikingly bright display;

  abundant repeat blooming, flowers are produced from late spring through fall, literally covering the bush with blooms;

  exceptional foliage health, glossy dark green leaves exhibit very high disease tolerance and a long-lasting attractive appearance;

  compact, vigorous habit that remains well-branched and easily managed

  butterfly and bee-friendly form, open-centered blooms and high nectar appeal tie into Barni’s “Butterflies” series, making it especially suited for wildlife gardens.

COMPARISON WITH PARENTS

COMPARISON WITH THE CLOSEST COMMERCIALLY AVAILABLE CULTIVAR

The closest comparable rose in commerce is perhaps ’Bayerngold’, a yellow Floribunda introduced by Tantau in 1990. Both roses share vivid golden blooms and excellent health, but there are clear differences. ’Bayerngold’ is more compact, only about 50 - 60 cm tall, and produces a double, cup-shaped flower, whereas 'Ali Dorate' is taller, 70 - 90 cm, and semi-double in a flat rosette form. The colour of ’Bayerngold’ is a warm gold and does not fade, while 'Ali Dorate'’s lemon tone is lighter and does fade to cream as flowers age. Both lack significant fragrance, but ’Bayerngold’ is often noted as virtually scentless, similar to 'Ali Dorate'. In terms of flowering, ’Bayerngold’ tends to bloom in very full flushes continuously, and is renowned as one of the healthiest yellow roses. 'Ali Dorate' also repeats well but its cycles can be more episodic; it makes up for this with slightly larger clusters, 5 - 15 blooms, and a fresher spring yellow.
