Joseph's Take
Hilda Niblett is dwarf and although is multi colored, would look nice surrounding itself with other dwarf azalea like Renee Michell or Conversation Piece. Think dwarf hedge surrounding a shady patio.

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.
