Persicaria capitata

Pink Knotweed

Persicaria capitata is a perennial herb native to regions spanning the Indian Subcontinent, Southeast Asia, and parts of China. It blooms from early to late summer, producing small, spherical flower heads that range from white to pink in color. These flowers appear in dense clusters, adding a soft, rounded texture to the plant. The plant's spreading habit allows it to form a dense groundcover that is both attractive and resilient.

Design tip

Use this spreading groundcover to soften the front of sunny borders or stabilize gentle slopes with colorful foliage and flowers. Surround it with upright perennials, graceful grasses, and flowering shrubs to create contrast, texture, and a natural flowing composition.
