Lantana, genus of more than 150 shrubs native to tropical America and Africa and belonging to the verbena family (Verbenaceae), order Lamiales. Common lantana (L. camara), growing to 3 metres (10 feet) tall, is a weed in tropical America, but elsewhere it is much used as a garden plant.

It blooms almost continuously with yellow, orange, pink, and white flower heads in various colour combinations. The aromatic leaves are rough and oval.

Trailing lantana (L. montevidensis), from South America, is a small-leaved, drooping, thinly branched species that bears rose-lavender flowers. Other species are variously known as yellow sage, weeping (or trailing) lantana, and polecat geranium.
