About this genus:
Persicaria is a genus of flowering plants in the knotweed family (Polygonaceae). Plants of the genus are known commonly as smartweeds, knotweed, fleece flower, or buckwheat. It has a cosmopolitan distribution, with species occurring nearly worldwide. The genus was recently segregated -so many of you old folk probably know it as Polygonum!
The genus Persicaria has many weedy species and somewhat of a bad reputation. However, as with any family, there are always some good members. We think we have found them!
Persicaria leaves are often multi-colored and often marked with dark centers and silver chevrons. This versatile genus will most likely grow anywhere that isn't a pond or a dark room. Other than an occasional haircut Persicaria is a low maintenance plant, that seems to look at home anywhere you plant it.
