more blossoms

Ok, as you may have noticed, I am really into this blossom kick this year... I can't seem to get enough of them! Perhaps it's the rare week of full sunshine we have had up here, so now that I am actually outside more, I am noticing them all around me. I think this one is a plum tree? Not sure... I am not that great at identifying flora yet. If anyone out there knows what this is, let me know!
