Buddleja davidii 'White Profusion'
'White Profusion' crown, Longstock Park, UK
Buddleja davidii 'White Profusion' is probably the most popular of the white cultivars, introduced to commerce in 1945 and still regarded as one of the best. Accorded the RHS Award of Garden Merit (record 681) in 1993, the award was reaffirmed in 2010 at the conclusion of the 2008-2010 Buddleja cultivar trials at Wisley. 
'White Profusion' is of a relatively compact and bushy habit  typically growing to a height of 2 m if kept hard pruned annually. The arching stems bear large, 30–35 cm long, dense panicles of pure white flowers; the foliage is an unremarkable plain green.
