Gardeners' Notes:

I have had VERY good success growing Rocket rhododendron in fairly deep dry shade under tall trees and it still stays dense, not at all thin or leggy. It blooms quite well with the limited light. The folage is very attractive year round, deep shiny green. Here in southwestern Pennsylvania the plants went through a more harsh than average winter in their first year with absolutely no damage, planted in the open and exposed to all the wind. The one gallon plants had some blooms when purchased and bloomed freely in the second season. I reccommend it highly as it is a great plant that needs no care to always be attractive.

One parent is 'Cunningham White', a hybrid of, R. caucasicum, which is native to the Caucasus of Eastern Europe. The other parent is R. catawbiense which is a native of southeastern United States with a range extending from Virginia to Georgia and Alabama. I have it planted in almost full shade and it has continued to produce flowers very well.
