That's why I kill most of my azaleas...and try to stay away from them. But sometimes I can't help myself. It's been growing outside for most of the spring and summer..went into the greenhouse 2 weeks ago.Most azaleas can't handle below zone 6 or 7 cold. As Penumbra stated there are very few that can withstand down to zone 5. Not sure if what you are seeing is normal seasonal color change or something else
I didn't scroll up to see the flower pics. My bad. And yes that is why I asked. So bi color leaves mean bi color flowers cool! Thanks Glaucus. I think it was from you I learned about the red vrs yellow leaf thing too.
