when you first noticed flowering trees? Think about it.
I had an apple tree in my back yard when I was a kid and I sure never noticed its blossoms. Later, living in my 20s on Manhattan’s upper west side, where the medians were a jungle of pear trees, I remember having the certain knowledge that all the blooms popped open the same night. It was a romantic view and I was a romantic.
Much later, when we lived in the Cabin, we had a magnolia that survived a late winter storm, but one hefty branch fell off, into the marsh below.
It was early spring, the tree was still in bud, and as the weather warmed up, the fallen branch blossomed as generously as the tree itself. It was another kind of romance, the romance of a miracle.
What flowering tree did you see first?

My father was into gardening. We had two Mountain Ash trees that had bright orange berries in the Fall. My father sprained that he planted the trees for the birds. Then he planted a couple of plum trees but we moved before they gave any fruit. This was all before I was ten, so I was aware of trees fairly young.
