Purple Gem rhododendron

Rhododendron 'Purple Gem'

Rhododendron 'Purple Gem' is a compact evergreen shrub with rounded clusters of violet to pale purple flowers in mid to late spring. Its small blue-green leaves may turn bronze in winter, giving it interest beyond bloom. Height is generally about 1 to 2 feet, while its eventual width is more variable; allow room for the plant to spread. Set it in a border or container with dappled shade and shelter from winter sun and wind. Moist, well-drained acidic soil suits its roots, and summer dry spells may call for watering in Southwest Washington. Keep it away from people or pets likely to eat it.

The right plant, the right place

Make room for something good.

Its compact evergreen habit suits borders and containers. Spring flower clusters provide the main display, while the small leaves may develop bronze tones in winter.

Where to plant

Choose dappled shade and shelter from winter sun and wind. Allow for spread beyond the plant's compact height, particularly beside paths or other shrubs.

Through the seasons

Violet to pale purple flowers appear in mid to late spring. Blue-green evergreen leaves may take on bronze tones in winter.

Southwest Washington gardens

Give it a good start.

A Puget Sound nursery lists 'Purple Gem', though its performance in Southwest Washington has not been documented in a local trial. Rhododendrons generally grow well in the Pacific Northwest.

Soil, drainage & water

Plant in moist, well-drained acidic soil. Water during summer dry spells to keep the root area moist without leaving it soggy.

A little care goes a long way

Growing well, season after season.

Shape after flowering if needed; this compact shrub generally needs little pruning. Check leaves periodically for lace bugs, especially where the plant receives more sun.
