Looking for confirmation on this to add to the database. The tag simply said azalea yellow. Any ideas?

It's at a nursery or other type of store? If so, I doubt it's a wild species as they are typically only sold by native plant specialists. On the other hand, there are a multitude of azalea cultivars which big box stores, in particular, sell generically by color. In other words, they don't care what which cultivar it is as long as it's yellow (or pink or white or whatever).

There are a few cultivars of R. austrinum on the market: http://www.malloynursery.com/n...

edited to add: I submitted proposals to have them added to the database.

Thank you Kent and Lin. I called my friend at the nursery where I got these two Azaleas. He said that they are un-named hybrids using native stock and grown by a local (in state) grower. He said that is why they were tagged "Azalea deciduous Pink" and "Azalea deciduous Yellow" and had basic growing info included. The grower only had a few of each and they all showed varying traits of the parents, but R austrinum and R canescens are included in the lineage but he is not sure at what point.

From what I was able to determine from my own researching, Southern native rhododendrons/azaleas are a rather "friendly" lot and there is quite a bit of cross pollination which accounts for the diversity in color.

I think that solves both of these threads... I have a lovely pair of deciduous azaleas that like morning sun, dappled shade and bloom in late March to mid April.

Again, thanks to you both.
