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]

Cultivation

"Tolerates most soils and conditions, including poor soils and amongst the roots and under the drip of trees[11, 200]." [PFAF]

Propagation

"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]

KEY TO SYMPHORICARPOS

1. Stems trailing and rooting at the nodes, the branches rising less than 50 cm................S. hesperius
1. Stems erect, more or less branching, 0.3-3 m tall.
2. Corollas relatively long and narrow, the lobes not more than half the length of the tubes..............S. oreophilus
2. Corollas relatively short and wide, the lobes nearly equalling the tubes.
3. Styles elongate, exserted slightly from the corolla tube, usually long-hairy near the middle.............S. occidentalis
3. Styles short, not exserted from the corolla tube, glabrous.
