Deciduous & Flowering Shrubs

Girard's Crimson azalea

Rhododendron 'Girard's Crimson'

Girard's Crimson azalea is a compact evergreen shrub with purple-red to crimson flowers in mid to late spring. Its foliage may turn copper-red in winter, giving this small plant another seasonal change. Expect it to reach about 2 to 4 feet tall and 3 to 4 feet wide at maturity; allow for that width when placing it near a path or other shrubs. In Southwest Washington, choose a site with partial shade and moist, well-drained acidic soil. Keep the root area moist during dry spells without leaving the soil waterlogged. Its low, spreading size suits the front of a shrub planting.
