Yes, Azalea indica

Thank you! does indica refer to the striped coloration?

Nope, just a species name, from India (name), even though from Japan originally....one of those 'misnomers'.

Thank you!!

Ah, those pictures reminded me of an Encore Azalea called Autumn Chiffon that I saw just last weekend. But that Encore does not have pink streaks like yours, just a similar pink color in the center of the Encore's bloom. Enjoy your indica.

Would A indica (Rhododendron indicum) grow outdoors in Tennessee?

In zone 7b, yes.

It looks a bit like Azalea 'Ben Morrison'.

I found an interesting article about trying to ID a similar looking azalea https://www.azaleas.org/wp-content/uploads/azalean/36/1/articles/My_Orphan_Azalea_-_Scot_Henney.pdf

"Ben Morrison" was a contender as was "Antoinette Martin" in this discussion.

Antoinette Martin was chosen for the masthead of the azaleas.org website and looks pretty similar to me.

There are so many beautiful Indica azaleas all in full magnificent flower right now in the South. I am in Athens, GA, not far from Augusta National Golf Club famous for its azaleas. No frost (so far) to frazzle them.

Thank you very much! I had no idea this website existed. this is very interested information.
