A rambling plant that doesn't have much above ground to recommend it to a garden, here is is growing in my deep-bed scrambling over Japanese Indigo. (Growing it in a deep bed means you can get at the roots easier)
It is quite an easy plant to grow and withstood the winter of 2008/9 which was our coldest for a long time. The stems have little soft spikes that enable it to cling like goose grass, but they do not hurt.
The root gives the best red dye ever!
a few seeds are currently available.
