A friend gave me several plants of this cultivar in 2002 - one mixed with ligularia. I planted all in moist but well drained soil in shade, and they've lived over even the 2003-2004 winter (very severe) and put on a real show each spring, with virually no care. The one mixed in with the ligularia is especially nice.

Foliage beautiful Rough and hairy, but with reflective silver leaves, green marginand midrib. Rosy flowers. Hardiness to be determined in my zone 5 garden. Rated zone 3-7. I have it in a moist bed in part shade and it seems to be thriving.
