Well, it turns out they are cherry trees with bookoo blooms! (I have been saying 'bookoo' all my life but don't remember where I heard the phrase. I'm sure it's an Americanization of French.) Anyway, it has been quite windy these last few days and the grass is covered with tiny white petals. The wind finally died down so I could get some photos and I think they look so great against the blue sky.
Grace had no intention of letting me shoot alone.
