Persicaria polymorpha, commonly known as Giant Knotweed or White Polygonum, is a bold, clump-forming perennial prized for its dramatic size and long-lasting white flower spikes. Reaching up to 4-6 feet (1.2-1.8 meters) tall, it produces dense, feathery plumes of small white flowers that bloom in mid to late summer. Thriving in full sun to partial shade and well-drained soil, Persicaria polymorpha is perfect for garden borders, mass plantings, or as a focal point in large garden spaces. Hardy in USDA zones 4-8, it adds height, texture, and a soft, airy element to the landscape.

Description

Persicaria polymorpha is an impressive and architectural perennial known for its towering, feathery spikes of white flowers that emerge in mid to late summer. These delicate blooms are clustered in dense, plume-like formations, creating a striking contrast against the plant’s broad, lance-shaped green leaves. The plant’s tall, upright growth habit makes it ideal for adding vertical interest and a touch of softness to garden beds and borders.

Preferring full sun to partial shade and moist, well-drained soil, Persicaria polymorpha is an excellent choice for adding texture and seasonal interest to the garden. Hardy in USDA zones 4-8, it is easy to grow and relatively low-maintenance once established. Whether used as a backdrop in mixed plantings, a specimen plant, or as part of a naturalized garden, Persicaria polymorpha brings both beauty and height to any landscape.
