Persicaria affinis - Knotweed
A lush, mat‑forming perennial, Persicaria affinis creates a carpet of narrow, dark green leaves that glow with bronze‑red tones in autumn. From midsummer it sends up numerous bottle‑brush spikes of pale pink that deepen to rose‑pink and stay in place well into winter, offering long seasonal interest. Ideal for edging, rock gardens, or under shrubs, it’s both low‑maintenance and elegant, self‑spreading gently without becoming invasive. Native to the Himalayas, this hardy plant adapts beautifully to Canadian gardens, thriving in sun to part‑shade with moist, well‑drained soil.
