Good close-up of Spiraea albiflora, the White Japanese Spirea. Spiraea alba is an American species with spike-like flower clusers.

Spiraea albiflora is now a synonym for S. japonica, so I'll wait a couple of days and then move the photo to the S. japonica entry unless @Char responds to this thread with other instructions.

We actually had a discussion about the images Dave and I had posted awhile back.
The thread "Spiraea alba?" in Plant ID forum
No one ever replied with an answer so nothing was moved at that time. I agree, my image can and should be moved.

Thank you, Char. I have moved the photo. Incidentally, you mentioned S. japonica var. albiflora as a possible ID in the other thread. It also is now only a synonym for S. japonica.
