Abstract
The new and distinct plant of Buddleia ‘Lilac Cascade’ is a rounded-mounded, multi-stemmed, winter-hardy butterfly bush with very long, narrow, outwardly drooping flowering thyrse producing a waterfall effect over a long season beginning mid-summer with sweetly-fragrant flowers of pale lilac petals that are attractively offset by dark green foliage with silvery undersides. No seed has been observed since development. The new plant is valuable for landscaping en masse, as an accent or as a potted specimen.
