Smooth Witherod

Looking for a shrub with great fall foliage and showy fruits? Smooth witherod, a native viburnum, readily provides those ornamental features and more.

Witherod grows as a large, upright, shrub with several main stems. The handsome oblong leaves are glossy dark green in the summer and develop rich burgundy red tones in autumn. In spring, smooth witherod bears large flat clusters of small creamy white flowers. These are followed by many small, plump, oval fruits. In early to mid autumn the fruits change from green to light yellow, then pink and ultimately dark Navy blue, often with multiple colors appearing together. Smooth witherod is a fine choice for woodland gardens, rain gardens, and other naturalistic landscapes.

Garden notes

  • Like many viburnums, smooth witherod is typically not self-fruitful so it’s best to plant a combination of several cultivars and/or the straight species to ensure cross pollination for good fruit set.
  • Smooth witherod’s tolerance of moist soil makes it a great choice for rain gardens or pondside plantings.
  • Combine smooth witherod in mixed plantings with fall-blooming perennials and ornamental grasses.

All in the family

  • Smooth witherod is a member of the muskroot family (Adoxaceae), a small group of plants that were previously included in the honeysuckle family (Caprifoliaceae).
  • There are more than 150 species of viburnum, many of them valued as ornamental landscape plants.
  • Witherod viburnum (V. cassinoides) is a closely related species (in fact it’s sometimes listed as a variety of V. nudum) that has a more northern range and can be grown through Zone 3.
