Establishment: S. boothii is found throughout western United States and Canada in montane and subalpine riparian areas. Cuttings are collected from stooling beds that are hedged to maintain juvenile wood that is straight and for ease of handling and sticking in field beds. Wild collections are also grown at our nursery and kept separated according to source.
