Corrigo Giant (Cornus nuttalli 'Corigo Giant')

All the nuttallis are native to the NW and I don’t suggest them for any other area. They are very susceptible to anthracnose even in the NW but , as they are large trees, people don’t look at them too carefully, and at a distance they are pretty spectacular with their large white flowers, often with a fall bloom also, and good fall color. zone 6.
