Western blue flax
A profusion of sky-blue, five petaled, shallowly cupped blossoms flower in late spring and into summer. Growing 12 to 18 inches tall with slender stems and narrow leaves. Can be short lived but often reseeds. A lovely filler, whose true blue flower color seems to go with everything, and the fine foliage contrasts nicely with a variety of leaf colors and shapes. Plant in full sun with moderate to infrequent summer water. Deer resistant.
