While crocus and daffodils are early blooming flowers, I have seen them covered with snow, making them unreliable harbingers of spring. But cherry blossoms come a little later and usually wait for reliably warmer weather!
The cherry trees around the tidal basin in Washington, D.C., reached peak bloom last Friday. I had visited the area on Monday, when most of the trees were still sporting buds. I stopped and sketched a tree, and while I was sketching a family walked by. The knots, lumps, deep crevice, and pronounced slant all made this an ideal climbing tree, and up scampered the little boy.
I came home and imagined what it would have looked like had the tree been in bloom.
What event signals the beginning of spring to you?
