Purple Willow

About Purple Willow in Alberta

Purple willow is an introduced Eurasian osier willow treated here as Salix purpurea, with Alberta relevance centered on cultivation rather than native ecology. In Alberta it belongs mainly to designed landscapes, bioswales, stormwater plantings, and specialty shrub use, and it should not be framed as part of the native willow flora. For Ancient Roots Alberta, its heritage value is most likely to come from older ornamental or institutional plantings, long-standing designed landscapes, and uncommon persistence of specialty willow plantings rather than from wild remnant habitat.

Identification: Leaves are narrow, lanceolate to linear-lanceolate, giving the plant a fine-textured look. Lower surfaces can be glaucous. An unusually important clue is that leaves may be opposite, subopposite, or alternate, unlike the strictly alternate pattern expected in many willows.

Alberta range and habitat: The safest Alberta interpretation is that purple willow is present mainly through planting. Broad wild occurrence is not supported in the current dossier, and any localized persistence or escape should be treated cautiously rather than assumed.
