Rhododendron
Rhododendrons are reliable, beautifully flowering, evergreen shrubs of variable origin: S.W. China, Himalayas, Northern America, and even Europe. The original species were hybridized several times for better performance so in the 1950´s there were more than 10,000 cultivars registered, and the number keeps increasing.Description of the plant:
Edith Hachmann is the wife of Hans Hachmann (1930-2004), a prominent German breeder, whose son Holger took over the mantle at a young age and continues the breeding of rhododendrons. On his mother's 90th birthday, he decided to name his newest beautiful creation with splendidly red flowers in her honour. It was launched on May 7, 2022, under the guidance of John Langley, a well-known garden ambassador who promotes ecological gardening and provides advice and tips at various public events and exhibitions.Edith Hachmann rhododendron is a large-flowered hybrid with deep ruby red flowers and all the qualities you expect from a good rhododendron. The flowers are large, conspicuously spotted with dark maroon to black spots and blotches, and the contrast is enhanced even more by the stamens with conspicuous white anthers. They open from the first decade of May in upright clusters and do not suffer from rain damage. Even outside of the flowering season, Edith Hachmann is a beautiful shrub thanks to its attractive leaves. They are evergreen, dark green, large, leathery, and slightly curled. It grows moderately fast to fast into a sturdy and upright shape, reaching a height and width of around 1.4 m at 10 years of age. The variety is healthy and blooms regularly and abundantly.
For a better-looking plant deadhead where possible. The roots are shallow, spreading to sides in search for nutrients. Never plant them too deep. The soil must be acidic (pH 4.5-5.5), rich in humus, cool and always moist but well-drained. Ideal soil mixture is peat with lime-free, light garden soil topped with leaf-mould. It is hardy to min. -27°C (USDA zone 5b).
