Azaleas are attractive shrubs known for showy blooms, and the Orange Macrantha Azalea, or Rhododendron indica 'Macrantha Orange’, doesn’t disappoint. The bell-shaped flowers measure 2 inches wide and are a vivid pinkish-orange shade. The rounded petals gently curl open, revealing pronounced stamens. This shrub reblooms, providing plenty of opportunities to enjoy showy flowers. Tiny, bright green foliage gives the shrub a full and lush appearance.
Create an eye-catching foundation planting or border, define a space, or add a hedge around a deck or outdoor entertaining area with this shrub. Plant underneath a shade tree to add a burst of color to the dim space. The showy blooms make the Orange Macrantha Azalea a focal point, but it also coordinates well in a mixed bed with other blooming shrubs and perennials. Grow the Orange Macrantha Azalea in zones 7 through 9.
Orange Macrantha Azalea Care
The Orange Macrantha Azalea needs rich, acidic, well-drained soil and full to partial sun. Mature, established plants are drought tolerant and only need water during an extended dry period. Apply a slow-release fertilizer for acid-loving shrubs at the start of the growing season.
This Azalea naturally maintains a pleasant, rounded form, and pruning is unnecessary. Remove dead or damaged growth as needed. Apply a thick layer of mulch around the base of the shrub in the fall to protect against winter temperatures.
Orange Macrantha Azalea Spacing
Orange Macrantha Azalea shrubs reach 2 to 3 feet tall and 3 to 4 feet wide. Plant shrubs 3 to 4 feet apart, center on center, to create a hedge.

?
"Blooms on" tells you which stems produce flowers, which decides when it's safe to prune.
- New Wood: Flowers form on stems that grow this season. Prune in late winter or early spring without losing blooms.
- Old Wood: Flower buds form on last year's stems. Prune right after flowering. Pruning in fall or early spring removes next year's blooms.
- Both New and Old Wood: Blooms on last year's stems and again on new growth, so it flowers even after a hard winter or a mistimed pruning. Prune lightly after the first flush of blooms.
