Persicaria microcephala 'Red Dragon'

You'll have to keep abreast of its growth, or it will smother the Hosta with exuberance!

The hosta in francis williams so a strong grower but I will keep a eye on it

Good contrast with the foliage around it.

thanks Terra it goes well with the two dark red acers

Yes.. I can imagine that must look great.

I adore this plant. It isn't a monster as long as you prune it back hard in Winter.

We prune it all through the Summer as it would become a giant here and keep falling over.....
