Camassia leichtlinii var. suksdorfii (Leichtlin's or Great Camas)
A robust spring-blooming perennial with bright blue flowers, our native camas once clothed Oregon valleys in waves of striking color. Settlement and agriculture over the past 150 years have pushed it to marginal small pockets in wetlands, roadsides, and areas unsuited to cropping. Two ft. tall in blossom. Occasional nectar species for Fenders Blue Butterfly.
With intensely blue, starry flowers in dense spikes in a carefree package the camas is a useful addition to gardens. It will gently reseed itself given light shade to full sun and some spring moisture. Dormancy starts in June so it is a great candidate for mixing with other perennials. 18 in. tall. Occasional nectar species for Fenders Blue Butterfly.
The leaves are tough, dark, grass-like, and nearly evergreen on this showy iris. It blooms in a spectacular color range from almost white to purple and all hues of blue in between. It is clump forming, blooming April-May, it is only 14 in. tall. This is an excellent, easy, very drought tolerant garden plant that is used far too infrequently. Nectar species for Dusky Wing and, occasionally, Fenders Blue Butterfly.
Blue-eyed grass is a key component of our wet prairies. The deep-blue flowers attract bees early in the day but close by mid-morning making them hard to spot in the landscape. The dark, clustered seed heads and slender, iris-like leaves make it reappear when the prairie turns a golden-tan in mid-summer.
This early blooming species has delicate blue flowers nestled in tufts of dark green leaves. In a wildlife garden, the long-bloom period makes it a great bedding plant. Hookedspur violet is a used a both a nectar and larval host for a variety of butterflies. It does best on upland restoration sites where competition from invasive plants and grassy thatch are kept to a minimum. 4-8 inches tall.
