There was a big red book, when I was little, full of fairy tales. One of the stories was about a giant, and an orchard and winter and blossoms. I forget the details, but it was very sad. But this is exactly what his trees looked like. Like every other human who passed it, I was drawn under the pink branches and we all looked up and pointed our cameras.
Each bloom is pendulous, all are clustered thickly together. Prunus "Okame".
The main event is probably about two weeks off, but other cherries are opening gradually. The Sakura Matsuri Festival is on the weekend of April 30th and I think the blossoms may still be hanging on - last year they had peaked and fallen. A warm day like tomorrow changes everything, though. Flower time speeds up, slows down, unpredictably.
