Persicaria

Persicaria - Knotweed

Persicaria is a genus of very useful, most hardy perennials which mainly flower late in summer. Persicaria will grow in any good soil in the sun or half shade. Especially the species Persicaria amplexicaulis (tall) and Persicaria affinis (low) are good weed suppressors. Once established, these species of Persicaria only need a tidy up in spring and some fresh compost annually. The species Persicaria microcephala and Persicaria virginiana are mainly used because of their beautiful foliage in the border or for flower arranging. Persicaria has many uses and should be present in every garden. Insects are also charmed by Persicaria.
