What a great idea, Lyn. I wish someone near me would offer to help weed in exchange for rhizomes. I hope someone sees your notice and takes you up on your offer. You would both benefit and make friends at the same time. Contact your local iris club. We often have members who send an email out telling what weeks they are digging and if you go and help that day you can have some of everything dug. It is often fun and educational to work in a garden other than your own.
