<human>:  I have a question about a plant called verbena. Why is it called verbena?
<bot>: Verbena is a genus of flowering plants in the mint family. The name comes from the Latin verbena, which means “to heal”. Verbena is a genus of about 100 species of flowering plants, most of which are native to the Americas. The most common species is Verbena bonariensis, which is also known as verbena.
