Persicaria – Bistorta Superba 2 litres

For those difficult situations, under large trees for example when all you want is  a carpet of something rather than bare weed ridden soil. We have found that they do need regular water until they are established but after that, growth is quick and wonderful… Long, fat spikes of baby pink flowers on slender stems above lovely weed excluding leaves. This is actually a member of the knot weed family, a great carpeter, which is considered semi-evergreen and will keep some foliage throughout the coldest winter.
