Hank's Iris Garden in Chino. I was going to give you her website, but I contacted her this afternoon and she's changing her site. I've known her for years through Dave's Garden (where you can check her rating under their 'Garden Watchdog)and gotten lots of iris from her. Everything is $5.oo. This is her e-mail address...

Thank you, wcgypsy, I'll email her and get the address and hours.

Ask any neighbor with Iris. The darn things multiply like rabbits. Start with one, end up with gazillions.

Yes, make sure you don't buy just any old iris. Check into the habits of each one, because they vary a lot in bloom periods, vigor, scent, "substance" (how long the flower lasts) and rebloom.

You can buy irises in flower right now from Matilija Nursery in Moorpark, about an hour away from where you are. Bob and Bonnie Sussman have a big selection of native plants and they also sell irises, mostly rebloomers and Pacific Coast Native irises, but also Louisianas and Spurias, if memory serves. Look online first and choose ones you like, then ask over at the iris forum for opinions on growth and vigor. I do not buy irises that are touted for vigor. I don't like dividing them every year. Also be on the lookout for leaf spot. You do not want to buy irises that have it. The big online sellers like Schreiner's and Mid-America Gardens and Napa Country Iris sell clean rhizomes.
