Re: CULT: and HYB: TB's in general....

Also some cultivars produce much smaller rhizomes than others. There are a
quite a few Blyht irises that produce very small rhizomes. eg Yes, Witches
Wand, Aztec Burst, and plus of course others  such as Bev Sills. I grow
Aztec Burst right next to Sneak Preview and there is always a marked
difference in rhizome size.
