Iris Setosa Arctica

This bone-hardy, very cold tolerant, grassy leaved Iris species which is native to Siberia and Alaska forms a low tuft of bright green, sword-shaped leaves. Many three-petalled flowers, lavender-blue with silvery-white veining, appear in late spring. It is a good choice for edging or in the sunny rock garden and can be very effective when mass planted as ground cover.
