I think I may have finally identified this as Prunus Glandulosa "Alba Plena". http://www.ces.ncsu.edu/depts/hort/consumer/factsheets/shrubs/cultivars/prunus_gland-albaplena.html
I don't remember a scent Droopy, but I'll be sticking my nose into it when I get back to work on Tuesday! I had quite a time trying to identify this plant. It seems no one has ever seen one before!
I like it, I've never seen a white flowering almond before. I knew those leaves looked familiar but the white blooms threw me off.
I'll do my best Sjoerd. My camera doesn't always focus on small blooms! Edited to add-I found one more photo that shows the bloom a bit better Sjoerd.
Nettie I missed this post.That is a pretty little flower.My Flowering Almond has pink blooms but looks like your blooms just different color blooms.
