Check out your neighbours gardens. Do they have rhododendrons or camellias growing in free soil? If they have blue hydrangeas then that is also a good sign.
I almost went blind looking at a pair of small leaved azaleas I have by the front door. They are decades old, one purple one pink and the colour contrast with the new bright green leaves is just stunning at this time of year. I normally have a large leaved yellow variety (Rhododendron Luteum?) as a backdrop which is a powerful combination particularly against the purple variety but I pruned that one hard last year to get it back under control. So I can see the attraction.
