Comments: Growing in the photographer's garden in northern California. I planted seeds more than 9 years ago and have been trying to figure out how to get it to bloom. Putting the container in a refrigerator for 3 months did the trick! I also have a second clone from another collection in bud. These iris grow in arid regions of central Asia. They protect themselves from the elements by locating their rhizomes 6 inches underground and have extensive root systems below that. For that reason, they need rather large planters; I can only fit one planter this large in a refrigerator. (D. Kramb, 15-JUN-12)
