    Flowers are gorgeous intricately marked flat affairs much freer blooming than the variegated form, that extra chlorophyll definitely helps. Zone- 7

    By: Arrowhead Alpines

    A clumping evergreen perennial. Fans of sword-like leaves from dense clumps. In Spring to Summer sprays of delicate pale blue to white, small, crested, iris flowers are produced. One of the easiest and daintiest of all the Iris to grow, just feed it well and don't let it dry out and it will reward you with hundreds of flowers.
