I've been disappointed with the flower displays of the kousas around here.
I've seen spectacular blooms on Long Island, prompting me to plant several here.
Our cornus floridas bloom great, but kousas sparingly.
Pictured is bloom from cornus kousa Satomi from this year.
To get 3 blooms in a picture was remarkable enough to take a picture,
which tells you how sparsely it blooms!
I've speculated they need more sun than c. florida to bloom well (mine are understory),
but it's just speculation. Maybe the wide temperature fluctuations/late frosts, etc also contribute.
