Rosa'Veilchenblau' is a mauve hybrid multiflora rose cultivar and the best known violet rambler. [2] Other names are 'Bleu-Violet', [1] 'Blue Rambler', 'Blue Rosalie' and 'Violet Blue'.

The cultivar was bred by Hermann Kiese in Germany in 1909. Its parents are the red hybrid multiflora 'Crimson Rambler' (Japan, before 1893) and the mauve hybrid setigera 'Souvenir de Brod' (Geschwind, 1884). It was introduced by Johann Christoph Schmidt from Erfurt, where Kiese had been employed until he started his own nursery in 1904.

'Veilchenblau' has small, semi-double flowers with an average diameter of 3 to 4 centimetres (1.2 to 1.6 in) [2] [3] and a sweet, fruity fragrance reminiscent of lily-of-the-valley. [4]

The crimson buds appear in late spring and early summer (June to July) in loose clusters of 10 to 30, and open to dark, purple violet flowers with a white center, that age to a grayish mauve, especially under hot conditions. [1] As they remain long on the plant, all hues can appear simultaneously. The cultivar blooms abundantly for a period of three to four weeks. [3] In autumn, 'Veilchenblau' develops small brown-red hips of only 5 to 10 mm length, decorating the shrub into the winter. [2] [3]

The cultivar is a robust, near-thornless rambler, growing from 3 to 6 metres (10′ to 20′) in height, but can reach heights of over 10 metres. [3] It has large, glossy, light to medium green foliage, [4] tolerates heat, [5] half-shade and poor soils, and is winter hardy up to −29 °C (USDA zone 5), but should be planted in airy locations, as it is susceptible to mildew. [6] The cultivar was used as stock plant and in rose hybridisation, and is easy to propagate through cuttings. Some of its seedlings are from the beginning of the 20th century are 'Rose Marie Viaud' (Igoult, 1924), 'Violette' (Turbat, 1921), 'Schloß Friedenstein' (Schmidt, 1915), and 'Mosel' (Lambert, 1920).

In 1993, 'Veilchenblau' was granted the Award of Garden Merit by the Royal Horticultural Society.

The site of Harison's villa is now just south of the present General Post Office. The nurseryman William Prince of Flushing, Long Island took cuttings and marketed the rose in 1830. 'Harison's Yellow' is naturalized at abandoned house sites through the west and is found as a feral rose along the Oregon Trail.

Garden roses Ornamental roses

Garden roses are predominantly hybrid roses that are grown as ornamental plants in private or public gardens. They are one of the most popular and widely cultivated groups of flowering plants, especially in temperate climates. Numerous cultivars have been produced, especially over the last two centuries, though roses have been known in the garden for millennia beforehand. While most garden roses are grown for their flowers, some are also valued for other reasons, such as having ornamental fruit, providing ground cover, or for hedging.

'Blush Noisette' arose as a seedling from the light pink rose hybrid 'Champney's Pink Cluster', introduced by Champneys around 1811, and was the first frost-hardy climber flowering repeatedly, giving the cultivar importance as a parent rose.

Basics of blue flower colouration

Blue flower colour was always associated with something unusual and desired. Blue roses especially were assumed to be a dream that cannot be realised. Blue colour in flower petals is caused by anthocyanins, which are members of flavonoid class metabolites. We can diversify three main classes of anthocyanin pigments: cyaniding type responsible for red coloration, pelargonidin type responsible for orange colour and delphinidin type responsible for violet/blue flower and fruits coloration. The main difference in the structure of listed anthocyanins type is the number of hydroxyl groups in the B-ring of the anthocyanin. Nevertheless in the monomeric state anthocyanins never show blue colour in the weak acidic and neutral pH. The mechanism of blue colour formation are very complicated in most cases, presence of delphinidin type pigments is not sufficient, great role play also the pH and the formation of complexes of anthocyanins with flavones and metal ions.
