CRANBROOK, British Colombia — At the Nupqu Native Plant Nursery in the Canadian province of British Columbia, sulfur buckwheat seedlings fill Styrofoam trays. …Sulfur buckwheat (Eriogonum umbellatum) is a high-altitude grassland species and one of the most in-demand species for restoration of highly degraded land, says Melanie Redman, the nursery’s seed specialist. But it’s also notoriously tricky to propagate. …Nupqu, which means “black bear” in the Ktunaxa language, is a wholly Ktunaxa-owned land and natural resource management company, part of a number of businesses jointly owned by the four Ktunaxa First Nations in Canada and the Ktunaxa Nation Council. Five years ago, the company acquired an existing native plant nursery, located on the ʔaq̓am reserve, and has since been building up expertise and capacity. The Nupqu Native Plant Nursery, which says it’s the largest Indigenous-owned native plant nursery in Canada, now cultivates more than 60 plant species.
