Distribution – China, Hunan province.
Description - A vigorous evergreen medium sized species which has spreading rhizomatous roots. The dark glossy green leaves are composed of three leaflets with conspicuous spiny margins and an acuminate tip. The flowers are of a good size and have a strong bicolour effect with white inner sepals and the petals are reddish purple.
This seems to be an easy and tough plant in the woodland garden, which will tolerate deep shade, but almost certainly at the expense of flowering potential.
