Here are two pictures that tell a tale:

This is the very same clump of Iris Reticulata in the same garden. The bloom this year is two and half weeks earlier. Projecting that forward and barring a surprise bitter cold snap, I have some planning to do! When friends ask, when is your Iris bloom party, I usually say, the first weekend in June. This year maybe the 2nd or 3rd weekend in May is a better bet.
