what azalea blooms same time as Delaware Valley white

Question

Would like to see white and crimson or deep pink together.

Answer 1

Most Azalea varieties bloom April to May including the Delaware Valley White.
You would virtually have hundreds to choose from!

You should know that my research shows that the Delaware Valley White cultivator is not reliably hardy in zone 5.
