The bearded iris rhizomes are about $3 each, sold in boxes of 15. I'd suggest going to the July 16 rhizome sale instead -- you'll get fresher rhizomes, grown locally. Prices may have gone up to $2 per rhizome, up to $5 for newer introductions and japanese irises... we can pick up some extra blue/purple for those who are interested.
Feedback and Rosalee F. are both good, sturdy varieties, so Lisa & Chantell if you want to try one or both, I'll add them to our order... but I'd rather talk you into coming up for the sale, maybe going to lunch afterwards!
