Abstract
The new and distinct plant of Buddleia ‘Princess Pink’ is a rounded-mounded, multi-stemmed, winter-hardy butterfly bush with very long, mostly horizontal, thyrse producing sweetly fragrant flowers over a long season beginning mid-summer. Flowers have large petals of purplish-pink that are attractively offset by dark green foliage with silvery undersides. The new plant is valuable for attracting butterflies in the garden, landscaping en masse, as an accent or as a potted specimen.
