Rhododendron calendulaceum, better known as Flame Azalea.  They have brilliant yellow to orange flowers.  I've seen several different colors.  All beautiful!!

 

They are native to our Appalachian mountains, and range from New York to Alabama.   They grow in deciduous forests and on the edges of the forest.  

 

Flame Azaleas are blooming all over our neighborhood right now, so be sure to notice them in your travels.

 

 

HAPPY GARDENING!!!
