Verbena Family (Verbenaceae)
North American Species
A number of species of wildflowers in the verbena family occur naturally in North America, or have been introduced from elsewhere and have spread to natural habitats.
One of the more familiar native species of verbenas in North America is the blue vervain or wild hyssop (Verbena hastata), a common plant of moist, temperate habitats. The French or Bermuda mulberry (Callicarpa americana) is a native shrub of moist thickets in southern parts of North America.
The European vervain or berbine (Verbena officinalis) is a common, introduced species in North America, and is sometimes an important weed.
