Q.We have pale green dogwood blooms…yuk! Want white!
I bought a Kousa full sun dogwood 9 years ago. It was moved 3 times before it found the right spot. It took 3 years to have blooms. Now it blooms; but it blooms later than all the other dogwoods in the Atlanta area (which is OK) BUT it blooms pale green blooms so I never have the bright white lovely blooms I planted it to have! Is there anything that can be done to get white blooms?

Here is an extension article that says the bracts of the Kousa start out small and are lime colored and expanding. The true flower is in the center of the bract and is insignificant. They bloom later than the flowering dogwood species.
Do yours eventually turn white?
Here is information on their care that may promote better bract color:
