Verbesina virginica (White crownbeard)

Verbesina virginica, commonly called frostweed or white crownbeard, is a tall, native perennial that occurs uncommonly in Virginia, predominantly near the coast, with sparce populations in the westernmost corner of the state. It inhabits woodlands and forest clearings, being adapted to part sun, but will grow in full sun as well.

 

In fall, frostweed sends up dense clusters of white flowers with irregular petals that provide valuable nectar and pollen from August to October. The blooms are highly attractive to bumblebees and butterflies.

 

In early winter, the plant exudes sap from its stem base that freezes into delicate ribbons of ice, forming “frost flowers,” a striking visual phenomenon that gives the plant its common name. Other species of Verbesina produce frost flowers, but Verbesina virginica in particular is known for this oddity of nature.

 

Its tolerance for part shade and ability to thrive in various soil conditions make it a great candidate for restoration projects, woodland edges, and low-maintenance wildflower gardens. Its tall stature also adds vertical structure, and the frost flower display offers unique winter interest in native landscapes.

 

All Verbesina spread well by reseeding, and will form a colony or stand over time, and may be best suited to wild or naturalizing gardens. To reduce population spread, remove seed heads after blooming is finished. However, the seed is also eaten by over wintering birds that live in and stop by our gardens.
