Buddleja davidii

'Black Knight', Longstock Park, UK
Cultivar 'Black Knight'
Origin Ruys, Dedemsvaart, Netherlands

Buddleja davidii 'Black Knight' has been one of the most successful davidii cultivars ever released. A selection made by Ruys at the Moerheim Nursery, Dedemsvaart, Netherlands, circa 1959, it was accorded the RHS Award of Garden Merit (record 676) in 1993.[1]

Description

'Black Knight' grows to a height of 4.0 m. The cultivar is distinguished by its deep purple flowers, reckoned to be the darkest of all the davidii cultivars, but the panicles, at 15–20 cm in length, are smaller than the type. Moreover, the medium-green leaves do not complement the flowers. [2] [3]

Cultivation

'Black Knight' is widely cultivated on both sides of the Atlantic. Hardiness: RHS H5, USDA zones 5–9.[1]
