We have three hybrid native azaleas from Gregory Bald, in Great Smoky Mountains National Park, planted below our deck. Two are a lovely coral pink color --luminous in the morning and evening. The diversity of hybrid flame azaleas on Gregory Bald is legendary.
A third is a deep orange color, much smaller. I've posted about it in the past, or a relative; we're now thinking that it's a replacement!
Our plants came from a small nursery owner who had grown them from seed. The flower color variation in seedlings is impressive (as are the variations in the natural hybrid population).
