About this cultivar:
Persicaria affinis 'Superba' It is a low-growing, mat-forming perennial that grows a few inches tall and spreads indefinitely by trailing stems to form an attractive ground cover. This cultivar ‘Superba’ is also considered to be synonymous with ‘Dimity’and is one of my favourite plants. We have near streams, in a wall, in borders- everywhere. It spreads but doesn't take over. It keeps weeds down without become invasive and even if it does, it is easy to pull out. It is tough and the leaves often go a wonderful red-green colour before turning bronze in autumn.

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.
