Add standout spring color to your landscape with Rhododendron 'Landmark' (Rhododendron 'Landmark'), a compact, broad evergreen shrub known for showy trusses of rich pink to fuchsia flowers with red spotting. You will also appreciate the small, dark green leaves that take on bronze to mahogany tones in winter, adding interest well beyond bloom season.
Plant it where your soil is organically rich, consistently moist, and acidic, with excellent drainage. A layer of mulch helps keep roots cool and conserves moisture, but keep mulch back from the crown. In dry periods, water deeply; rhododendrons have fine, shallow roots that dislike drying out or sitting in water.
For best performance, give it partial shade or gentle morning sun with afternoon shade, and protect it from drying winter winds. This selection is more sun-tolerant than many rhododendrons, but strong afternoon sun can still stress foliage and buds, especially in warmer areas.
At maturity, expect a height around 60-72 inches, making it useful as a foundation plant, accent, or low screen. Place it where you can enjoy its spring flowers and winter leaf color, and pair it with other acid-loving companions for a cohesive woodland-style planting.
Prune only as needed right after flowering to preserve next year's buds. Feed lightly with an acid-forming fertilizer after bloom if your soil needs it, and monitor for chlorosis if your soil is too alkaline.
