Summary
Crisp white flowers over dark evergreen leaves, on a rhododendron that stays a manageable size.
Chionoides is an older, proven rhododendron grown for its clean look. In late spring it covers itself in rounded trusses of white flowers, each marked with a small yellow blotch in the throat. Against the dark green foliage, the blooms stand out even in the shade of tall trees.
The plant grows slowly into a dense mound about four to five feet tall and a little wider, keeping its leaves all year. That size and shape make it easy to place along a foundation, at the edge of a woodland bed, or in a row as an informal evergreen hedge.
It also handles more sun than many rhododendrons, as long as its roots stay cool and moist. That gives it a wider range of uses than the classic shade-only types, including brighter foundation beds on the east side of a house.
Care
Chionoides Rhododendron Care
Plant in partial shade to full sun. Morning sun with afternoon shade is ideal; in full sun, keep the soil evenly moist and mulched to prevent leaf scorch. Shelter from strong winter wind helps protect the evergreen leaves.
Rhododendrons need acidic, well-drained soil rich in organic matter, ideally around pH 4.5 to 6. Work in compost or composted pine bark when planting, and set the root ball slightly above the surrounding grade, since the roots rot in soggy or compacted ground. Heavy clay is best avoided or amended generously.
Water deeply once or twice a week through the first growing season while roots establish, and during dry spells after that. The roots are shallow, so a two-to-three-inch layer of pine bark or shredded leaf mulch helps keep them cool and moist. Water well in late fall before the ground freezes.
Feed lightly in early spring with a slow release fertilizer made for acid-loving plants.
Prune only if needed, right after flowering, since next year’s buds form over the summer. Snapping off the faded flower trusses is optional but tidies the plant; take care not to damage the new shoots just below them.

Additional Information
Can it grow in full sun?
It handles more sun than many rhododendrons, but it still does best with some afternoon shade, especially in the warmer part of its range. In a sunny spot, mulch well and keep the soil evenly moist through summer to prevent leaf scorch.
Why are my rhododendron leaves curling in winter?
Rhododendron leaves curl and droop in cold weather to reduce moisture loss. This is normal, and they unroll when temperatures rise. Watering well in late fall and siting the plant out of strong winter wind helps reduce winter browning. For more plants that hold their leaves year-round, see our Evergreen Plants.
Is it a good choice for a foundation planting?
Yes. Its slow growth and mounded shape keep it in scale under windows for many years, and the evergreen leaves give the front of the house structure in winter. Plant it where gutters and downspouts will not keep the soil soggy. For more foundation options, see our Shrubs & Bushes.
Do deer eat rhododendrons?
Deer do browse rhododendrons, especially in winter when other food is scarce. In areas with heavy deer pressure, protect plants with netting or repellent. If deer are a constant problem, consider our Deer-Resistant Shrubs and Evergreens instead.
