We have serviceberrys all around the house in the woods, maybe more than a dozen. One is near to the house. But I don’t know which kind of serviceberry it is. Berries are very small and the birds especially the cardinals really enjoy them. And you are right the blooms are great to see in the early spring.
When they produce well, I find that serviceberrys AKA Saskatoons are great for jam. No pectin needed. You have to run them through a food mill to get the seeds out, and the juice, etc. tries to jell on its own right then and there.
