The tag on this one simply said azalea pink. We have R canescens, Honeysuckle azalea, growing wild here in Louisiana. Unfortunately the rain got to this one before I could get better pictures. Its' growth pattern and shape are very much like images of R canescens and R austrinum.

See my comments about your other azalea. Unless it's being sold by a nursery that specializes in native plants, it's unlikely to be a wild species.

Thanks Kent. Just a lovely pink deciduous hybrid.
