Vervain and verveine are other names for the genus Verbena, which belongs to the Verbenaceae family. About 150 kinds of annual, perennial, herbaceous, or semi-woody blooming plants are found there. The leaves are typically opposite, straightforward, and frequently thickly hairy in several species. Small, five-petaled flowers are borne in dense spikes. They are often some shade of blue, although, especially in cultivars, they can also be white, pink, or purple. Additionally, verbena has been utilized in aromatherapy and as a herbal tonic over the years.
