Every day this week, I have eagerly examined the red maple tree that grows in the yard next door. The weather has been mild and sunny, quintessential spring, and each evening I've been certain that it would finally be the day: the maple would flower. Tuesday I had a long field day, arriving home from a day trip to another state at 9:30 pm. Murphy's Law would suggest that would be the day the tree would flower, but a Wednesday morning inspection revealed otherwise. I started to get impatient: the crocuses are blooming, as are the Siberian squill. What the hell?
Finally! Today was the day... I got to report my first observation. First flower is defined on the phenopause page as the date the first flowers are completely open. "You must be able to see the stamens among the unfolded petals." Full flower is a separate event to report, which is probably good in this case. I didn't traipse too far into my neighbors' yard, but I only saw two flowers that were completely open. No matter--I see stamens. What is flowering in your yard?
