Ethnobotany

"...once much used by native Americans."[DPL Watts] The plant was valued for external use because it contains saponins. "These saponins can be toxic, but when applied externally they have a gentle cleansing and healing effect upon the skin, killing body parasites and helping in the healing of wounds." [PFAF]

"Stored seed requires 3 months warm then 5 months cold stratification[98]." "Cuttings of mature wood, 15 - 25cm long preferably with a heel, in a sheltered bed outdoors in winter. High percentage[78, 200]. Division of suckers in winter." [Unspecified][PFAF]
