    Iris tectorum is a vigorous grower in my 7b north Georgia garden. From a small root transplant which I bought from the local Master Gardeners sale, I have propagated it throughout my garden, each transplant growing into a full round and blooming in a single season. It grows in full sun and also part shade equally well, with no watering, no disease, no pests, no fertilizer. I have acidic clay soil. Good "filler" plant, with purple blooms in spring and architectural foliage until frost.
