Lantana, of the vervain family Verbenaceae, consists of more than 150 species of shrubs and herbaceous perennials. Lantanas are hairy and often prickly-stemmed. If rubbed and bruised their leaves usually have a disagreeable odor. Verbena-like flowers are formed in stalked clusters or spikes from the leaf axils or at the ends of branches. The juicy, berry-like fruits contain two nutlets, often called seeds. In some regions, Texas included, lantanas are troublesome weeds, chiefly spread by birds that are very fond of their juicy fruits. The species name, horrida, refers to the pungent, unpleasant odor of the crushed leaves and the "out-of-control" weed potential of the plant.
