Gardeners' Notes:

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.
