Award-winning Buddleja davidii 'White Profusion' (Butterfly Bush) is a vigorous deciduous shrub with gracefully arching branches, studded with lance-shaped, gray-green leaves with white-felted undersides, and sweetly scented panicles of snow-white flowers. Borne at the tips of the current year's growth, the outstanding flower spikes, up to 8 in. long (20 cm), are on display from mid-summer through early fall and sometimes to the first frost. A superb, easily-grown plant that is favoured by butterflies and provides late summer to fall flowers when few other shrubs are in bloom.
