Bring jewel-tone color to your landscape with Rhododendron × 'Midnight Ruby' (Rhododendron 'Midnight Ruby'), a compact, broadleaf evergreen shrub prized for early-season clusters of rich reddish-purple to ruby-red blooms and handsome foliage that deepens to burgundy tones in cold weather.
At maturity, you can expect a dense, rounded plant about 24-36 inches tall with a similar spread, making it easy to tuck into foundation beds, mixed borders, or mass plantings where you want reliable structure year-round.
For best results, site it where it receives bright light with protection from harsh afternoon sun. Part shade is ideal, though it can tolerate more sun in cooler climates when the soil stays evenly moist. Provide well-drained, humus-rich, acidic soil and refresh a mulch layer to help conserve moisture and protect shallow roots.
Water deeply during establishment and during dry spells, especially in summer. Avoid soggy sites and standing water. If you fertilize, use an acid-forming product formulated for rhododendrons and apply according to label directions in spring.
Minimal pruning is needed. If you shape the plant, do so right after flowering so you do not remove next season's buds. In exposed locations, evergreen leaves can benefit from wind protection during winter to reduce drying.
