About Koenigia lapathifolia (Cham. & Schltdl.) M.H.J.van der Meer
Koenigia lapathifolia (Cham. & Schltdl.) M.H.J.van der Meer is a herbaceous or semi-evergreen perennial. It grows up to 2 meters (almost 7 feet) tall, with a woody root and lanceolate leaves. It produces abundant white, cream, or pale green flowers that are borne in plumes during midsummer. These flowers are followed by pinkish seed-heads later in summer or early autumn. In garden cultivation, plants are usually cut back after flowering to preserve their vigour. This species, previously referenced as Koenigia alaskana, is native to Alaska, the Yukon, and Magadan Oblast in the Russian Far East. It is cultivated in spaces large enough to accommodate its substantial mounds of foliage. Cultivated under the name Persicaria alpina, it has received the Royal Horticultural Society's Award of Garden Merit.
