Best low-growing azaleas?
I'm looking for the best (in mostly shade, New England) low (in height) growing azaleas. I saw a picture years ago of one in a catalog with a gorgeous low, horizontal growth habit. By low I mean no more than about 2 feet, would love width (sort of a low "sprawl"?) I've seen a number listed as good options, including Kiusinanum(s?), Hilda Nibblet, Yuka, Nancy of Robinhill and others.
I want a natural look. The one I saw pictured years ago (and failed to note the name of, sadly) was in a rock garden and had a beautiful layered horizontal look on a low plant.
Any recommendations? We're zone 6 (but on the edge of a 5) in Connecticut. These will share space (in front of) a larger Cunningham white rhodie and a (blossom gall-prone!!) Weston's native azalea, along with a beautiful Deutzia Slender. Any color would work -- the house is a soft gray and all three of these current plants have white bloom (so I DO want some color, just don't care what it is).
Thanks in advance!
