Name: greene Savannah, GA (Sunset 28) (Zone 8b) I have no use for internet bullies!
If it's blooming now there is a double-flower Bridal Wreath Spirea/Spiraea prunifolia...but that may just be wishful thinking on my part. Always wanted one of those plants in my garden.
Sunset Zone 28, AHS Heat Zone 9, USDA zone 8b~"Leaf of Faith"
