Each month, we will feature one of the plants on the Time to Restore list. Frostweed (Verbesina virginica) has been identified as a priority species in Texas. The range of this species spans from Texas and Oklahoma east to Florida and up into the lower Midwest. This is one of two species in the Verbesina genus on our Texas priority list; the other species is Verbesina encelioides, cowpen daisy, also known as golden crownbeard.
Frostweed is named for its tendency to exude water when temperatures drop below freezing. The water is pushed out of small holes in the stems, often forming ice crystals in fascinating shapes.
You can observe this species as a single plant in Nature's Notebook. If you have more than one plant, consider monitoring 2-3 individuals at the same site to capture the variation between plants. If you have multiple plants growing together that are difficult to differentiate, register the plant as a patch and make your observation considering the patch as a whole.
When considering flowers for frostweed, ignore the larger white ray flowers and focus on the small disk flowers that contain the reproductive structures.
For the plant pictured below, you would report:
Flowers or flower buds - yes
Open flowers - yes
Fruits - no
Ripe fruits - no
