Range: the Central Valley of California. Additional info: the range in coloration may be due partly to hybridization with other native species, common among western irises.
I am an avid fan of Adoree and her lineage, and this wonderful hybrid from Paul is perhaps the best of the ones I've been lucky enough to grow and observe. Besides the gorgeous and uniquely similar color pattern of Barry's Valley of Dreams, what makes this hybrid special is the vigorous/ prolific growth compared to Adoree, and the tall, strong bloom spikes that tower up in the garden and with beaming pride announces its magnificence when it first begins to bloom. This quickly moved up into my top ten (and anyone who's been growing Irises for five years or longer knows that this is a pretty special group and that, depending on the day, the positions are all interchangeable).

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.
