Keywords: Themidaceae | Triteleia grandiflora Lindl. var. grandiflora | White Lake Grasslands Protected Area, near Okanagan Falls, British Columbia, Canada
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).
The southwestern North American Themidaceae, including Triteleia, are closely related to the onion family, the Alliaceae.
Link of interest: Something I missed pointing out last week was that a demographic tipping point had been reached (symbolically) on May 23: the day the world's human population became more urban than rural.

wonderful soft photos of this plant, Daniel. You must have been down on your belly to get these shots -- that's how I spend alot of my time when I'm out with the camera while my companions are far ahead on the trail. ;-)

Yes, on my belly or sitting down. That was one of the nice things about the field trips at Botany BC - they weren't "we must reach X by Y". Instead, they were move at your own pace and enjoy + learn about what you see.
