Rhododendron diversipilosum 'Milky Way'
Rhododendron diversipilosum 'Milky Way'
Rhododendron diversipilosum 'Milky Way' is a low evergreen shrub with white flowers in spring. It generally reaches about 3 feet tall and 3–5 feet wide, making room at the front of a shrub border or along a path where its mature spread will fit. In Southwest Washington, give it acidic, well-drained soil and steady moisture, especially through summer dry spells. A site with partial shade and protection from strong afternoon sun suits general rhododendron guidance. The flowers may appear in April locally, though timing will vary with the season. Mulch the root area to help keep moisture even.

The right plant, the right place
Make room for something good.
Its low evergreen form can fit near the front of a shrub border or beside a path. Allow for a mature spread of about 3–5 feet.
Where to plant
Choose a site with partial shade and protection from strong afternoon sun. Give the shrub enough room to reach its mature width without crowding a path.
Through the seasons
White flowers appear in spring; an Oregon nursery reports April bloom. The foliage remains evergreen.
Southwest Washington gardens
Give it a good start.
In Southwest Washington, water during summer dry spells to maintain even moisture. Drainage also matters through wet periods, when saturated soil can favor root rot.
Soil, drainage & water
Plant in acidic, well-drained soil and keep moisture even. Water during dry summer weather without leaving the roots in saturated soil.
A little care goes a long way
Growing well, season after season.
Mulch around the shrub to help maintain even soil moisture. If pruning is needed, do it soon after flowering.
Know what to look for
Common growing concerns.
Symptoms can have more than one cause. These notes are a starting point for observing your plant and improving its growing conditions.
Phytophthora root rot
Stunted growth, yellowish-green leaves, wilting, branch dieback, and rotting roots.
Help your plant thrive
Start with disease-free plants and well-drained soil. Remove and destroy infected plants rather than leaving them in the bed.
Rhododendron lace bug
Pale stippling above the leaves and dark, crusty deposits beneath them; repeated infestations may yellow foliage.
