Rhododendron 'Holden's Solar Flair' is an evergreen rhododendron with striking spring color and a tidy, upright habit. You will enjoy rose-pink buds that open into soft yellow flower trusses marked with a bold red blotch, set against deep green foliage that holds its color year-round.
Give this plant a site with full sun to part shade; in warmer climates, your best results usually come from morning sun with afternoon shade and protection from harsh, drying winds. Plant it where it can stay cool and evenly moist, especially through its first few seasons while it establishes a strong root system.
For best performance, amend your planting area with plenty of organic matter and keep the soil acidic, rich, and well-drained. A 2-3 inch layer of mulch helps conserve moisture and moderates soil temperatures, but keep mulch pulled back slightly from the stems to reduce rot risk.
Water deeply during dry spells and avoid letting the root zone dry completely. If your soil is heavy clay, consider planting on a slight mound or in a raised bed to improve drainage. Avoid over-fertilizing; a gentle, slow-release fertilizer labeled for acid-loving shrubs is typically enough.
Prune only as needed, and do it right after flowering to preserve next year's buds. Remove spent flower clusters to keep the plant looking neat and to encourage healthy new growth. At maturity, expect a compact shrub about 36-48 inches tall, with a spread around 24-36 inches.
