Viburnum spp. This is a genus of popular flowering perennial landscape shrubs, with more than 150 varieties available. They bloom in spring, followed by attractive fruit and outstanding fall foliage. Fast-growing viburnums can grow one to two feet per year. These plants can be used as hedges, ground cover, a privacy fence, and more.

There is no single type of viburnum foliage. Leaves can be rounded, lance-shaped or toothed, smooth, velvety, or rough. There are multiple types of viburnum flowers, too: flat clusters of florets, flat umbels outlined with larger flowers, and dome-shaped, snowball-like clusters.
