Viburnums
Highbush Cranberries and Other Viburnums Viburnum spp.
The Viburnum genus encompasses more than 150 different species, which can range from dense shrubs lush with green foliage to more open and rangy small trees. Viburnums are prized for their multi-season interest, with blossom, berry and foliage varying by species. Flowers attract many butterflies and other early-season pollinators in spring. Ripening berries, some edible for humans, put on a show of color throughout the summer.
All the Viburnums we offer are important wildlife plants, native to eastern North America.
Growing Viburnums
- Soil: Adaptable, but in moist rich well-drained soil they will take on a fuller shape.
- Sun: Full sun to part shade.
- Pollination: Plant multiples of the same species for best fruit set.
- Pest Control: Viburnum leaf beetle (Pyrrhalta viburni) has become a problem in some areas. The larvae overwinter on twigs and can defoliate shrubs in spring and early summer. They seem to prefer Arrowwood, but we have seen them do a number on Wild Raisin and Nannyberry. Prune out and burn any egg-infested twigs in early spring before your shrubs are leafed out. Spraying with Spinosad in late April or early May when the larvae first emerge can also help. Timing is key—spraying eggs or adult beetles is less effective.
