IdentificationBrazilian Vervain is a quite familiar roadside "weed"; it is a 1-few-stemmed plant ranging to 7 feet tall, but normally is about 4-5 feet tall. The stem leaves are tapered basally (vs. sessile and clasping in V. bonariensis), sharply toothed and lance-shaped. The inflorescence consists of terminal and axillary shoots with flat-topped clusters of short spikes. These spikes have many tiny lavender to pale purple flowers. V. bonariensis also differs in its longer corolla tubes, and its flowers are a richer purple color.
