Lovely native wildflower of dry hillsides & grasslands in central interior British Columbia. Blooms open in sun & close tightly on cloudy days. Haven't seen it used in gardens around here; plants are slender & quite inconspicuous so I'm thinking it would be lost unless grown in a rockery in a group or colony. I much appreciate it in the wild in early to mid-summer...always seems to be blooming at the same time as the wild roses.

This is one of the largest-flowering of the 'blue-eyed grass' species; also one of the tallest. I've tried several species and this one so far has not been too invasive (others are quite nasty). Nice in a rockery or planted next to a yellow flowered or yellow foliaged plant.
