Johanna Azalea is a semi-dwarf reblooming evergreen shrub with dense glossy foliage that emerges light green and matures to emerald before it earns a burgundy tint in winter. Masses of ruffled deep red flowers bloom in spring attracting bees and butterflies. A very hardy plant that prefers partial sun with acidic rich, well-drained soils.

MAINTENANCE NEEDS: A low maintenance plant. Moderate water needs, properly drained soils is a must to avoid root rot. Mulch helps to keep roots from drying out. Keep away from drip lines of the walnut family. Acidify soils as needed (PH range of 5 to 6.5) Can use sulfur or iron sulfate to lower ph, and lime or limestone to raise PH. Southern climates with excessive humidity are more prone to powdery mildew, twig blights, and rust.
LANDSCAPE USES: Mass or Specimen Plantings, Woodland Gardens, Borders, Foundation Plantings, Hedges, and Containers.
COMPANION PLANTS: Fatsia, October Daphne, Astilbe
