Outstanding Qualities

"Persicaria polymorpha is a bold perennial that tolerates a wide range of conditions. Giant fleeceflower produces a large clump of 5-to-7-foot-tall leafy stems topped with large, fluffy, white flowers. The flowers are held over a long period in July and August and then develop into pinkish seed heads. The plant tolerates a variety of soils and does not require staking. Unlike other species of Persicaria, this is not considered invasive, though it does require some room to grow. Persicaria polymorpha is effective when used at the back of the border against a hedge or dark background. It combines well with Sambucus nigra 'Black Beauty' and large perennials and ornamental grasses. The name ""white dragon"" helps you imagine its stature and charm-both are considerable!"

Culture Notes
This robust large perennial prefers a rich moist to well drained soil. If the site is too dry it will wilt easily in the afternoon sun. The best flowering and growth is in full sun to light or open shade. In fall cut to the ground once the foliage starts to yellow. Provide ample room for it to grow to its full potential.
