One of the highlights for me of attending Botany BC was this plant, large-flowered triteleia (some references may use large-flowered brodiaea, due to a synonymous scientific name, Brodiaea douglasii). I hadn’t encountered it before, and to see it in large clusters of plants with a sagebrush background was mightily impressive. I later often encountered it in the Palouse hills, but in populations that were nowhere near as dense as these in the White Lake Grasslands Protected Area (photo of White Lake).
Triteleia grandiflora is a native of western North America; the Flora of North America account has a distribution map. The Plants for a Future database cites a source claiming it is “said by some people to be the tastiest of the North American edible bulbs” (making one wonder about those tasty inedible bulbs). In the southern interior of British Columbia, the bulbs were consumed by the Okanagan, Nlaka’pmx and St’at’imc peoples (source: Plants of Southern Interior BC).
