for your encouragement. this is a whole new venue for me in zone 10; not without many challenges. had to revamp my gardening skills, growing a lot more succulents and exotics now. (not too unfamiliar as i grew up with most of them)
Don't despair. Here is a picture of a successful grower out in the So Cal desert - Mystic Lake Gardens

Not only do they grow TB, they have rebloomers, lots. In Zone 10 you can get rebloom that we in the colder areas seldom see. They get reblooms from Oct to February. I don't think this grower is too far from you, relatively speaking. You might pay them a visit. They are very involved in the iris society and seem like lovely people. They use ebay to sell their iris and I've bought from them before.
