Cayuga Viburnum is a vigorous hybrid that has dense, very dark green, leathery summer foliage that speaks volumes in terms of selecting plants for their healthy season-long foliage, rather than for ephemeral flowers or other short-lived ornamental attributes. However, Cayuga Viburnum also has wonderfully fragrant inflorescences, being very large and prominently encased in dark crimson buds before they open.
