"Normally", whatever that means anymore, average last frost date here has been mid April, which means light frosts have happened even later. Hard freezes that have damaged early growth have often hit here in late March. Low 20's F.
This year, we haven't had any really hard freezes since Feb. A few light frosts, barely freezing. So irises haven't been set back at all since they started putting on spring growth. They look fantastic for a change here in the 'vale'.
Most years, germanica blooms first, then the SDBs, then pallida and any early TBs that have managed to escape being killed.
This year, the germanicas are well on their way to showing color, no sign of buds on the SDBs, but I'm starting to see stalks on a few TBs.
Two that have stalks up are either rebloomers or from rebloom breeding - RENOWN, which normally blooms mid season, and 2nd season to bloom TEA LEAVES X GOLDEN PANTHER.
The winter was long and miserable because it stayed cold rather than the more typical up and down, but it never got below 10oF.
So I'm wondering - are these stalks that "should" have bloomed last fall? I've never seen RENOWN try to bloom anywhere near this early. 

Just wondering...
