Butterfly bush 'Dartmoor'
'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. The weight of the large inflorescences causes the ends of the branches to droop, bestowing a distinctive, arching structure.
