Sea-Buckthorn

About Sea-Buckthorn in Alberta

Sea-Buckthorn is an introduced thorny shrub or small tree used in Alberta shelterbelts, edible plantings, acreage landscapes, and difficult sites. It is useful because it tolerates poor soils, fixes nitrogen, forms dense cover, and produces bright orange fruit, but Alberta-local guidance also warns that it can be extremely invasive where it spreads into surrounding natural ecosystems. For ARA, older plantings may have shelterbelt, food-garden, or soil-conservation history, but heritage value must be weighed against spread risk.

Identification: Leaves are narrow, linear to lance-shaped, and silvery green, with paler undersides that give the plant a gray-green cast from a distance.

Alberta range and habitat: Sea-Buckthorn is not native to Alberta. Alberta records are introduced, planted, and sometimes locally spreading from plantings.
