A few of my friends have had success storing cheaper end of season TB's this way. I've tried it with SDB's with about 75% success, just playing around with extras, to see if it worked. I buried them in vermiculite in the paper bags.

Subject: [iris-photos] CULT: strange storage
This is a blog from SpringHill. Read all the way down. In the 56 years I've raised irises, I've never heard of lifting and storing iris rhizomes in paper bags. Anyone else?
