What: Rhododendron ‘Vulcan’ blooms in late spring with trusses of bold fire-engine red against a backdrop of deep green foliage held on rounded shrub.
Where: This rhododendron is easy to grow in the Pacific Northwest. Plant it in rich well-drained or sandy soil in a location with full sun to light or open shade.
Size: Grows to 5 feet tall and 5 feet wide in 10 years.
Care: Rhododendrons are shallow-rooted plants requiring regular watering during dry weather. Faded flowers can be removed to give a cleaner look and new growth can be pinched to help make young plants bushier. Adult root weevils can chew on their leaves, but this is less of a problem on plants that receive more light and regular watering.
