Koenigia alpina

Koenigia alpina (synonym Aconogonon alpinum),[1] commonly known as alpine knotweed,[2] is similar to Koenigia alaskana, but differs in leaf size and achene characteristics.[3] It is native to Europe and temperate Asia.[1]

For the cultivar often known in horticulture as Polygonum polymorphum or Persicaria polymorpha, see Koenigia × fennica § 'Johanneswolke'.
