Azaleas in Bloom - April 2018 in My Neighborhood

Spring has sprung in Greensboro.  I have been taking a lot of images of azaleas in my neighborhood and at some parks/gardens.  There are so many colors and varieties.  The image on the left was taken after the rain as a close up and I like to call it Peppermint because of the color variations.   The image on the right is more like a rhododendron cluster of petals.  The yellow color is unusual. I have a similar type image of an orange flowering azalea but it was difficult to photograph because of chain link fence.  It was just begininng to bud and you can see the fine hairs on the stem.  I did apply a vignette to blur out background.

 I am still confused about the terminology of rhododendon and azalea.  All azaleas are rhododendrons.  Maybe this article will help and also provides info about growing them.
