Ecological Indicator Shade-tolerant. "Plentiful on Vancouver Island, sparse on [the] coastal mainland. Most frequent on water-shedding and water-receiving sites; commonly associated with Polystichum munitum."[IPBC] [E-flora]
Similar Species 2 species in genus: western North America, Japan.[Jepson] "The distinction between Achlys triphylla and A. californica, which often coexist, is not sharp. Some botanists think that recognition of A. californica is not warranted."[PWOBC] "We are not convinced that A. californica is worthy of recognition." [IFBC][E-flora] The two North American species are chromosomally different, morphological separated by microscope, and one occupies well-drained, often open upland sites. The other... deeply shaded sites on low bottomland forests". [Klinkenberg][E-flora] Both A. triphylla and A. triphylla ssp. japonica showed a "chemotaxonomically close relationship".[IInuma et al.]

Medicinal Uses

"The plant was used by native North Americans to treat anumber of health problems, though it is little used in modern herbalism[257, 270]."[PFAF]

Cultivation

"A woodland plant, it requires a position in semi-shade and a humus-rich soil[280]."[PFAF]

Propagation

Propagation:
"Seed - we have no information for this species, bu it is probably best sown as soon as it is ripe in a shady part of a cold frame. If stored seed is used, it should be sown as soon as it is received. Germination can be erratic. Prick out the seedlings as soon as they are large enough to handle and grow them on in a shady part of a greenhouse or cold frame for at least their first winter. Plant them out into their permanent positions during autumn or early winter. Division should be possible in early spring or just after flowering."[PFAF]
