Native to the southeast United States, occurring from Mississippi to Florida and north to Virginia. This is considered a wildflower and generally is not a noxious weed.
A perennial plant that reproduces from seeds. May be found commonly along roadsides and in natural or disturbed habitats, and may occasionally grow in landscape or other habitats where it may not be wanted.
Mature plants grow erect or sprawling, with several stems arising from the base of the plant. Stems are reddish, square in cross section, and stems and leaves have a rough, slightly hairy texture. The leaves are lance shaped and pointed at the tip, with lighter veins and red margins. Leaves are opposite and are either without stalks or are on very short stalks. Additional pairs of leaves may arise from the axils of the main leaves. Flowers also arise singly from the leaf axils, and these are large and showy, violet to bluish, and their 5 petals are joined at the bases to form a deep tube. The calyx around the base is composed of long, thin, pointed blades.
Characteristicts Important to Control:
Control is usually not necessary for this native wildflower, but physical removal is effective when it is found growing in an undesirable location.
