Hi all. I'm shopping for Siberian irises now, from Wildwood Gardens, which seems to have really good prices for these. My question is this: How many rhizomes of each should I buy? I assume that each plant is a single rhizome, and am just wondering if a single rhizome would be enough, or if I should get 2 or 3. What do you think? Thank you in advance for helping this iris neophyte!
