Collinsonia verticillata Bald. ex Ell. - Whorled Horsebalm
Family - Lamiaceae
Flowering - April - June.
Habitat - Wooded slopes, deciduous woods.
Origin - Native to North America.
Other information - This attractive species is uncommon in Alabama and can be found in just a handful of southern counties. The plant can be identified by its large opposite leaves. The nodes of the upper stem are very close together and give the leaves a whorled appearance. Any other than the upper four leaves are typically much reduced or absent all-together. The large inflorescences can get branched with age and the frilly white flowers are quite striking.
