Hi, This small understory tree blooms around the same time as forsythia, before the leaves come out, right now it has small mango shaped fruits, I haven't lived here long enough to know if any will grow larger and ripen.I have looked up fruit trees but can't find any matches. Anyone have an idea what it is?

I'm not a botanist and sure don't know about native species in the States but that looks like some kind of prunus flower. The bark looks like some kind of cherry. Leaves are similar to cherry. SO is the fruit a stone fruit ?

The fruits may not be growing much bigger - if indeed some kind of prunus - small fruit may be usefull. https://en.wikipedia.org/wiki/Kriek_lambic https://en.wikipedia.org/wiki/Sloe_gin etc....


I include a dutch determination key - based on that you can probably find a similar one in english.
