Persicaria Polymorpha Knotweed

Persicaria polymorpha, commonly known as White Fleece Flower, is a bold and statuesque perennial that brings height and elegance to the garden with its sturdy, branching stems and large, lance-shaped green leaves. In midsummer, it produces impressive plumes of creamy-white flowers that last for weeks, creating a soft, airy display that transitions into attractive pinkish-red seed heads later in the season. Forming a substantial clump, this low-maintenance plant is tolerant of heat, humidity, and even some drought once established. Non-invasive and long-lived, it is ideal for the back of borders, naturalized plantings, or as a flowering hedge, where it provides structure, movement, and lasting visual impact.
