Iris Setosa Alba

From May until early July, this stunning dwarf option to the taller irises produces disproportionately wide and large, ivory-white flowers which each have a contrasting inner halo. Flowers are held on sturdy stems above solid clumps of narrow, green sword-like leaves. Very cold tolerant, this short, grassy-leaved Iris species, native to Siberia and Alaska, is a perfect choice for edging, or in the sunny rock garden. It is also effective when mass planted as ground cover, when it will grow in sun or semi-shade, preferably in a moisture retentive position.
