Minnetonka rhododendron

Rhododendron 'Minnetonka'

Rhododendron 'Minnetonka' is a dense, low-growing evergreen shrub with lavender-pink to purple flowers marked by contrasting spots in midseason. It reaches about 3 feet tall and 4 feet wide at maturity; a ten-year plant may be closer to 2½ feet tall and 3 feet wide. Its compact form suits a shaded shrub border or a planting near a path where there is room for its full spread. In Southwest Washington, give it a sheltered site with dappled shade, acidic soil that drains well, and steady moisture through summer. Mulch over its shallow roots, and prune soon after flowering if shaping is needed.

The right plant, the right place

Make room for something good.

The dense, low-growing form fits a shaded shrub border or a planting near a path. Allow room for its roughly 4-foot mature spread.

Where to plant

Choose a sheltered position with dappled shade. Give the shrub space to widen without crowding a walkway or neighboring plants.

Through the seasons

Spotted lavender-pink to purple flowers appear in midseason. The foliage remains evergreen after bloom.

Southwest Washington gardens

Give it a good start.

In Southwest Washington, maintain moisture through dry summer weather. Check foliage for lace bug and watch for signs of root trouble where drainage is poor.

Soil, drainage & water

Plant in acidic, moist but well-drained soil. Water consistently through summer, especially while the shrub establishes.

A little care goes a long way

Growing well, season after season.

Mulch over the shallow roots to help retain moisture. If shaping is needed, prune soon after flowering so next year's buds can develop.
