Now if only I could grow TBI here. Maybe in pots. This year should tell.

Let's hope yours grow well. Sometimes (this winter) we had bitter cold called a "Polar Vortex" over the Midwest. Temperatures were sub-zero for weeks clear into March, and I am waiting to see if it affected the irises. So far it seems they are OK.

My heavens! I knew you had bad weather across the middle states but Polar Vortex. Wow! And we had the mildest winter on record for a long while. I do hope your plants all got tough and made it through in good shape.
