Evergreen

Rhododendron 'Rangoon'

Rhododendron 'Rangoon'

Rhododendron 'Rangoon' is a low, broad evergreen shrub with bright red flowers early to midway through the rhododendron bloom season. A nursery lists it at about 4 feet tall and 6 feet wide, giving it a wider footprint than its height suggests. Leave enough room for that spread in a sheltered planting, where its compact form can sit beneath taller shrubs or beside a path. Dappled or light shade and moist, acidic, well-drained soil suit general rhododendron needs. In Southwest Washington, water through extended summer dry spells and protect the foliage from hot afternoon sun, especially during heat.

Where to plant

Choose a sheltered site with dappled or light shade. Keep it out of hot afternoon sun, which can stress rhododendron foliage during warm weather.

Through the seasons

Rhododendrons generally grow well in the Pacific Northwest, but local performance of 'Rangoon' has not been established. Summer dry spells make watering especially useful.

Soil, drainage & water

Plant in moist, acidic, well-drained soil. Water regularly during dry weather without leaving the roots in saturated ground.

A little care goes a long way
