In my neighborhood, the blossom pattern is:
- purple-leaf plum trees bloom first; as they begin to leaf out
- green-leaf plum trees bloom next;
- single-blossom cherry blossoms then wait until all the fuss is over, so they can be the only ones blooming.
Double-blossom cherries follow that, but I don't have many of those in my neighborhood.
I still find it funny that I can walk over toward West Portal and still find purple-leaf plum trees with blossoms; it is like going back a month in time!
