Abstract
The new and distinct plant of Buddleia ‘Pink Cascade II’ is a rounded-mounded, multi-stemmed, winter-hardy butterfly bush with very long, broad, slightly pendulous flowering thyrse producing a waterfall effect over a long season beginning mid-summer with sweetly fragrant flowers of pinkish petals that are attractively offset by dark green foliage with silvery undersides. No seed has been observed on this plant and it is presumed to be sterile. The new plant is valuable for landscaping en masse, as an accent or as a potted specimen.
