Similar species: Two other varieties of Viburnum dentatumoccur in the Chicago Region: dentatum and scabrellum. Variety dentatum differs by having star-shaped hairs on the leaf stalks. Variety scabrellum differs by having hairy leaves and leaf stalks. Viburnum rafinesquianum is also similar but has stipules on the leaf stalks. Also, the leaves subtending the inflorescence of V. rafinesquianum have leaf stalks no longer than 7 mm.

Flowering: May to June

Habitat and ecology: Introduced from farther east. An increasingly common escape from cultivation, often found in disturbed woods and other disturbed areas.

Occurence in the Chicago region: non-native

Notes: About 200 species of Viburnum occur between North America, Europe and Asia. Many are ornamental shrubs cultivated for their showy flowers, autumn foliage, and attraction to wildlife.

Etymology: Viburnum is the Latin word for the Wayfaring tree. Dentatum means toothed. Lucidum means bright, lustrous, or clear.
