| Viburnum prunifolium
Blackhaw viburnumCulture: Tolerating full sun to moderate shade, this adaptable species can tolerate moist to dry soils with acidic to alkaline pH. It is easy to transplant and is somewhat pollution tolerant. Some pruning may be needed to remove suckers, but otherwise none is required. This species has few problems with insects and diseases, although scale insects and borers can occur. This viburnum is resistant to the leaf mildew that is so common on Viburnum lentago.Usage: In habit resembling a hawthorn, this species can be grown as a large shrub or small tree. It makes a great specimen or mass, or can be part of the shrub border. Relatively few cultivars are available and desirable selections need to be made. Viburnum rufidulum, the Rusty blackhaw viburnum, a closely related species, is the southern equivalent with highly glossy leaves and similar buds except that they are covered with short rusty-brown hairs. Selected from the Morton Arboretum through the Chicagoland Grows program, Viburnum rufidulum 'Morton', trademarked Emerald Charm, offers cold hardiness to Chicago, highly glossy foliage, excellent white flowers and burgundy fall color. |
