Buddleja davidii

Dartmoor

B. ‘Dartmoor’ is instantly recognizable by its unique magenta to light purple 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 (if left unpruned); however the green foliage is unremarkable and all but identical to the type. The weight of the large inflorescences causes the ends of the branches to droop, bestowing a distinctive arching structure.

Reduce height in November by 50% to prevent wind damage.

History

Buddleja Dartmoor’ is arguably the most unusual B. davidii cultivar ever raised. Cloned from a plant found growing in a small ravine on Dartmoor near Yelverton by a retired American gardener, Mr Hayles; the story goes that with his wife clinging onto him, Mr Hayles was able to reach down and grab some propagation material from the plant.

The shrub was introduced to commerce in 1973 and accorded the RHS Award of Garden Merit (record 678) in 1993 (reaffirmed 2010).
