Two days ago (May 27th) the Siberian irises bloomed. I looked up last year's bloom; it was on the 26th, a day earlier. But hey, last year was a leap year, so it works out to the same day, sort of. These plants know exactly what they're doing.
Today, we are in glorious sunshine, temperature in the low 20s (C). Hope the weather is as nice where you are.
