All the Bloomin' Day!

Julia and I took a walk around the neighborhood today. I took my camera, on the hunt for blooms. Trees in bloom, to be precise --
Here's the Japanese Magnolia, next door.

And the flowering quince. Love the deep salmon color. Yes, I know -- it's not actually a tree :)

I don't remember what this was, but it sure was glorious against that blue sky!

Now, I've adored this little tree for years, and always wanted to get a picture of it in bloom. I'm not sure, but I think this is the first year I've succeeded. Last year, the owners told me what type of tree it is, but memory deteriorates with age, and I do not recall. Julia remembered, however, that they did say it's not supposed to be a tree, but a bush. The owners have pruned it into a short tree. Isn't the bloom luscious? It's waxy like a magnolia, and has a lovely scent.

The unopened blooms look fuzzy, like pussywillow.

I like the contrast of it against the hemlock.

Here it is, full-size. Any helpful ideas as to its identity?
