Nursery contributed plant descriptions

Iris japonica is rare species known as fringed or crested iris. It has delicate, fragrant, orchid-like flowers that display ruffled white petals with fringed margins with pale blue markings and prominent yellow crests on the falls. The flowers are two inches in diametre and bloom from late spring to early summer. The evergreen foliage is thin with sword-shaped basal leaves that grow in fans with downward arching tips. Vigorous and naturalizes easily. Use in beds, borders, rock gardens, and containers and as a ground cover. Deer resistant. Possibly hardy to zone 6. Photo: Wikipedia.
Flowers are gorgeous intricately marked flat affairs much freer blooming than the variegated form, that extra chlorophyll definitely helps. Zone- 7
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.
