- Description
-
'Raulston Hardy' is a dwarf viburnum cultivar introduced by the J.C. Raulston Arboretum. Developed from the US-native Walter's viburnum (Viburnum obovatum), it is smaller, denser, and hardier than the species, forming a tight bush useful for landscaping. Its form lends itself as an alternative for boxwood species with the added bonus of white April-blooming flowers and black fruits loved by birds. It is evergreen to semi-evergreen, taking on some purple color in colder weather, though may become deciduous closer to zone 6.
Plant in full sun to partial shade in average, moist, acidic, well-drained soils. It is tolerant of both dry and wet soils, cold and drought, heat and humidity, and even salt and browsing by herbivores. Its small size lends itself to many landscape uses such as hedges, foundation plantings, containers, and even specimen plants.
Insects, Diseases, and Other Plant Problems: No serious problems.
The Clemson Cooperative Extension Home and Garden Information Center has a factsheet on common pests and diseases.
