Buddleja davidii 'Dartmoor'

Buddleja davidii
Cultivar 'Dartmoor'
Origin Dartmoor, UK

Buddleja davidii 'Dartmoor' is arguably the most unusual davidii cultivar ever raised. Reputedly cloned from a plant found growing in a small ravine on Dartmoor near Yelverton by a retired American gardener by the name of Hayles, the shrub was introduced to commerce in 1973 and accorded the RHS Award of Garden Merit (record 678) in 1993 (reaffirmed 2010). [1]

Description

'Dartmoor' is instantly recognizable by its unique magenta inflorescences comprising compound, branched panicles, 20–30 cm long, instead of the typical single, terminal spike. The shrub can grow up to 5 m in height, the green foliage unremarkable and all but identical to the type. [2] The weight of the large inflorescences causes the ends of the branches to droop, bestowing a distinctive, arching structure.

Cultivation

'Dartmoor' is now very common in cultivation on both sides of the Atlantic, and is hardy to - 15° C. Like most other davidii cultivars, it responds well to heavy pruning in spring. Hardiness: RHS H5, USDA zones 5–9. [1]
