Persicaria alpina (Alpine Knotweed) is a tall semi-evergreen, perennial boasting sturdy branching stems clothed with large, lance-shaped, green leaves. In midsummer, stately plumes of small creamy-white flowers are on display for weeks, if not months. They are followed by pinkish-red seed heads in late summer. Clump-forming and low maintenance, this spectacular perennial is tolerant of heat, humidity, and, once established, some drought. Unlike other species of Persicaria, it is not considered invasive, but it does require some room to grow. Perfect for the back of the border or as a flowering hedge.
