Koenigia alaskana (synonym Aconogonon alaskanum, Persicaria alpina) is an Asian and North American species of flowering plant in the buckwheat family known by the common names Alaska wild-rhubarb and alpine knotweed.[2]
This herbaceous or semi-evergreen[2] perennial grows up to 2 meters (almost 7 feet) tall, with a woody root and lanceolate leaves. The abundant flowers are white, cream or pale green, borne in plumes in midsummer.[3] They are followed by pinkish seed-heads later in summer or in early autumn. However, in a garden setting they are usually cut back after flowering to preserve vigour.[2]
Koenigia alaskana is native to Alaska, the Yukon, and Magadan Oblast in the Russian Far East.[1]
It is cultivated in areas with enough space for its substantial mounds of foliage. Under the name Persicaria alpina it has received the Royal Horticultural Society's Award of Garden Merit.[2]
