Chinzan Satsuki Azalea. "Satsuki" means "May" in Japanese which indicates when this group of Azaleas flower. This cultivar has small narrow leaves and is one of the most outstanding dwarf shrubs even when not in flower. But its flowers are a 2" medium pink to add to its charm.
If given adequate moisture, one can grow this selection in full sun, but probably best in morning sun and afternoon shade or filtered sun. But it needs uniform moisture. Many gardeners believe Azaleas need to be in part shade, but one will have a much heavier flower bud set in more sun.
A good azalea to bonsai!
