I have this tree in my front yard and I have no idea what it is. It leafs out early in the spring then some of the leaves on the ends turn into pink flowers (not like a typical blossoming tree) and eventually the middle of the flowers turns into a small fruit with an odd texture. The flowers have no smell to them and the fruit doesn't have a single large pit like a cherry or plum. I live near Seattle if that helps to place it in context at all. Here's a picture:
