Hello all you nice people who helped me figure out how to send photos. In the meantime, I contacted an online nursery by email and sent them my photos. They have identified the flower
as Oenothera (evening primrose, Blushing Rosie) It's a perennial and blooms in early spring
. Very beautiful. It can be planted in the fall (which I intend to do) and requires full sun. Can't wait to get them going.
