Common lantana is a shrub native to tropical America, with rounded clusters of small flowers that can change color as they age. The leaves and unripe fruit should not be eaten because they are poisonous. In U.S. gardens, the name common lantana may also be used for the similar Lantana strigocamara.
Flower color alone will not separate them. Lantana strigocamara often has leaves more than 2 in (5 cm) wide, but a leaf measurement alone will not securely identify either species.
Why they get mixed upBoth have rounded clusters of multicolored flowers, and U.S. garden labels have long mixed their names.
