The virus attacking native Cornus florida on the East Coast of the U.S. is
anthracnose. Apparently, the west coast species are even more susceptible
to it when planted in the east, so if/when the disease reaches the west
coast, look out. It is known as "dogwood anthracnose", so perhaps it is
somewhat species specific. Maybe someone else knows about that aspect.
There are hybrids between C. florida and C. kousa, known collectively as C.
X Rutgersensis, bred at Rutgers University, which are reported to resist
the virus. The commercially available series of these is the Constellation
series, with various named crosses. Cultural techniques do seem to, so far,
make a difference in keeping the native dogwoods from succumbing to
anthracnose: plenty of sun, freedom from competition, good air circulation,
and enough supplemental water to reduce drought stress. C. kousa seems
resistant to anthracnose.
