Red flowers have ruffled petals and bloom in clusters around mid-May, making Holden's Red Rhododendron a showpiece in a landscape. The colorful flower buds provide color and visual interest during the winter. When the bold red flowers open, the lighter-colored center gives the blooms dimension. 

Dark green leathery foliage comes to a rounded point, and as a broadleaf evergreen, the leaves stay in place throughout the winter. Holden's Red Rhododendron has a woody, well-branched growth habit and makes a wonderful hedge or foundation planting. Add height to the back of a mixed bed or create a springtime focal point. Pollinators are drawn to the spring flowers. This cultivar is disease resistant and grows in zones 5 through 8.

Holden's Red Rhododendron Care

Holden's Red Rhododendron grows best in full shade. Keep the soil moist but never soggy. Plant this shrub in rich soil that promotes drainage and has an acidic pH. Apply a thick layer of organic mulch around the base of the shrub to provide nutrients and keep the soil moist. Fertilize the plant every four to six weeks using a product intended for rhododendrons. 

Remove dead or damaged growth at any time. Shape the plant as needed after the flowers fade. Rhododendrons set flower buds early, so be careful not to prune late in the summer or fall because it may interfere with next year's flowers.

Holden's Red Rhododendron Spacing

Holden's Red Rhododendron stands 5 to 8 feet tall and 6 to 8 feet wide. Space shrubs 6 feet apart when creating a continuous hedge.
