It is true that I seem to notice this one when I'm driving around in the spring, its eye catching. I think it's because the flowers are bigger and the plant grows a bit bigger than most Azaleas. I usually plant these under a canopy of trees where they have room to spread. A great companion is sunglow azalea.
Be sure to use a well drained soil medium when planting any Azalea, Rhododendron, Mountain Laurel, or Camellia as they all prefer fall planting with less watering than you might think. In NC our soil is clay so we prefer to use pine bark soil conditioner when planting these varities.
