Blackhaw Viburnum


A large bush that I’ve been delighted to find is Blackhaw Viburnum (Viburnum prunifolium). It’s growing by my backdoor, and there’s lots of it growing in the woods all around my cabin.

The leaves of Blackhaw emerge from the buds involute, or curled as a spiral. The mature, glossy, opposite leaves are three to four inches long and one inch wide with fine serrations and pointed at the end. The petioles, or stems, of the leaves are a reddish color. In the autumn the leaves turn a purply-red.

Soon my bush will have buds. Buds that will become clusters of fragrant flowers four to five inches across. Flowers that will attract bees and flies to do their pollination magic.

Blackhaw Viburnum is the host plant of Spring and Summer Azure butterflies. The later caterpillar instars of the Baltimore Checkerspot butterfly occasionally feed on its leaves. Oh I wish I’d see a Baltimore Checkerspot butterfly! I’ve seen their caterpillars while pulling invasives in Shenandoah National Park. Never the adult though.

Its fruits, called drupes, are about one half inch long. They’re eaten by songbirds, gamebirds, squirrels and chipmunks.

As a tree Blackhaw Viburnum can grow to be thirty feet tall. Its bark blocky in a Persimmon tree sort of way. Large bush, small tree, all in all a mighty cool plant.

  1. I really enjoy your presentations and information. I’ve been a Viburnum enthusiast for decades and you add to my knowledge bank. Thanks so much, glad I signed up for eMails from you!

    • Hi Carolyn! I’m so happy to hear that you’re enjoying my posts. How wonderful that you take such pleasure in Viburnums. My back hill is quite wild since I live in the woods, and it was a wonderful surprise to realize that I have a Blackhaw Viburnum. It’s my intention to tidy up things back there so that I really know what I have!

      Thank you so very much for reading my posts. I enjoyed hearing from you.
