Azalea vs Rhododenron

I don't have any difficulty identifying azalea and rhododenron plants in my own garden. However, this week I visited a garden that had varieties I wasn't familiar with and I was no longer confident that I was identifying them correctly. So, I did a quick search and learned, to begin with, that while all azaleas are rhododendrons, not all rhododendrons are azaleas. Who knew?!

If you are like me and need a little help knowing the difference, I found this video to be very helpful.
