Best grown in average, medium to wet soils in full sun to part shade. A rhizomatous plant which may spread aggressively in the garden. Cut plants to the ground in late fall or winter.
This knotweed group consists of vigorous, upright variegated perennials which typically grows on pinkish, stems to 4-6' tall and spreads by rhizomes to form colonies. It is primarily grown for its bold, variegated foliage. Ovate green leaves (to 5" long) are attractively splashed with white. Tiny, greenish-white flowers appear in loose, tassel-like, axillary racemes in late summer, with the resulting seed plumes sometimes persisting into late fall.
No serious insect or disease problems.
Mass in shade, woodland or cottage gardens. Also may be used in borders.
