Deciduous & Flowering Shrubs

Gumpo White azalea

Rhododendron (Satsuki Group) 'Gumpo White'

Azalea 'Gumpo White' stays low and compact, with evergreen leaves and ruffled white flowers that may carry pink flecks in late spring. Gardeners in Southwest Washington can place it near the front of an acidic-soil planting, where its flowers are easy to see and its foliage remains through winter. Allow about 2 to 3 feet for its spread; height is often near 18 to 24 inches, though plants may grow taller. Choose partial shade and moist, well-drained acidic soil. Water during dry spells to keep the root area moist, and avoid sites where water stands. The plant is harmful if eaten.
