North American native rhododendrons typically thrive in filtered sunlight and acidic soil, but modern varieties can tolerate a wider range of conditions. It does best when planted in dappled shade on the north side of a building. Growing rhododendrons are happiest in a location protected from the wind and not under eves of a building. They thrive in growing zones 4 to 8.
I’ve wanted to have rhododendrons for several years but have never found them in local garden shops. Here in central Florida, I know a few people who have planted azaleas which is in the rhododendron family, but my attempts to raise azaleas have failed. These pretty photos are from a friend further north. I thank you Carole for sharing them.
