Iris cycloglossa is a broadleaf deciduous perennial bulb / corm / tuber with green foliage. In spring blue flowers emerge. Grows well with sun - mostly shade and even moisture - high water. Does well in gritty and well-drained soil. A good option if you're seeking something verticillium wilt resistant.
A fantastic Juno collected southwest of Herat in Afghanistan by Wendelbo in 1975 in a damp grassy habitat very unusual for a Juno, it is extremely local and endemic only to this one small region. It is also distinct in that it is the only Juno with upright standards. Flowers are blue with a distinctive clove scent, very weird for a Juno, they appear more xiphium-like than Juno; definitely not a plant for beginners. ZONE 5
