Visited Sun State Nursery, 17/92 in Longwood, FL a few days ago. They had a very pretty dwarf azalea variety - variegated dogwood. Has green leaves and a large..ish pink and white flower. While researching this variety I came across the south florida plant guide which talks about this variety and azaleas in general in very simple, easy to follow, terms. I think you will find it helpful.
