Camassia Lily
Here is a beautiful early season blue flower. This plant is a perennial planted from fall bulbs. They are hardy in zones 3-8. It is a wild flower in the western US. They’re are available in both blue and white. We have a smaller blue and the taller (18-22inch) blue variety. Both are so lovely to have in the late spring. The bloom for us at about the same time as lupine and the earliest allium and peonies. Other flowers that are blooming right now: viburnums, early roses, delphinium.
Our camassia bulbs came from Netherland Bulb Company (wholesale), but there are also retail providers online at a higher cost for those of your who are not selling your flowers.
