Persicaria (also known as fleece-flower or knotweed) brings tall, elegant spikes of blooms—ranging from creamy white to deep red—that flower from mid-summer into fall. These clump-forming plants thrive in Canadian gardens (hardy in zones 3-4 and up) when planted in full sun to part shade, in moist yet well-drained soil. Loved for their long bloom season, architectural presence and minimal maintenance, they work beautifully in cottage-style borders, naturalistic prairie plantings or mixed perennial beds. Browse our Wildwood Express Persicaria collection and add a dramatic, pollinator-friendly perennial that offers texture, height and enduring performance in your garden.
