Lantana is a genus of about 150 species of perennial flowering plants in the verbena family, Verbenaceae. They are native to tropical regions of the Americas and Africa but exist as an introduced species in numerous areas, especially in the Australian-Pacific region. The genus includes both herbaceous plants and shrubs growing to 0.5–2 m (1.6–6.6 ft) tall. Their common names are shrub verbenas or lantanas. The generic name originated in Late Latin, where it refers to the unrelated Viburnum lantana. Lantana's aromatic flower clusters (called umbels) are a mix of red, orange, yellow, or blue and white florets. Other colors exist as new varieties are being selected. The flowers typically change color as they mature, resulting in inflorescences that are two- or three-colored. A common name for Lantana camara is "Ham 'n Eggs" due to the adjacent pink and yellow inflorescences. "Wild lantanas" are plants of the unrelated genus Abronia, usually called "sand-verbenas".
