Frost Weed

Frost Weed (Verbesina virginica) is a flower in the Sunflower Family. It ranges from Texas to Florida and north as far as Pennsylvania. At times of subfreezing temperatures the sap will freeze and expand and the resulting pressure splits the main stem open. I've seen this before in the bottomlands but never took a photograph of this event. Following the recent cold snap that paralyzed a large portion of the country I walked in my back yard to find frozen sap on my dormant frost weeds. Frost Weed can grow to 6 feet.  With its 50 - 100 or more blossoms Frost Weed  is a good plant for bees but is a prolific seeder and can get weedy.
