Brick-red flowers cover this evergreen in spring, and the small glossy leaves turn deep wine-red through winter, which makes the foliage as much of a feature as the bloom. Rhododendron 'Stewartstonian' grows 5 to 6 feet tall and 4 to 5 feet wide in full sun to part sun, hardy from Zone 5 through Zone 8.
At five to six feet this is one of the larger evergreen azaleas, usable as an informal hedge or a screen.
The habit is upright and dense, holding its shape without pruning.
Acidic soil is necessary, roughly pH 4.5 to 6.0, with good drainage and steady moisture. Alkaline ground turns the foliage yellow. Mulch the shallow roots.
