Birth flower for August 21
Lantana
Meaning: Rigor and cooperation
Lantana's tiny flowers change color as they age — yellow to orange to red — so a single cluster glows in several shades at once. The shift is thought to signal butterflies which flowers still hold nectar. Pretty as it is, lantana is one of the world's most notorious invasive shrubs, spreading wild across Taiwan, Australia, India and other warm regions.
