Blooming right now is the lovely and delicate Kousa Dogwood (Cornus Kousa). It blooms later than the Florida type varieties which bloom before the leaves come out. My brother Brian Bergman (lily hybridizer) and Frank Kershaw (horticulturalist) have trees in bloom right now. The fruit that sets from these blooms is itself an interesting sight, and is edible.
I hope you get to see this delicate flower!
