Positive hillfarm On Nov 27, 2010, hillfarm from Quesnel, BC (Zone 4a) wrote:

Very early blooming wildflower of dry hillsides in the interior Cariboo region of British Columbia. Vibrant cobalt blue; like nothing else in the wild in this area. Very variable; tall or short; densely flowered or widely spaced. All are lovely. Would definitely be good in a dry rock garden type setting; might get lost in the mixed border.
