Flower image: Ageratum

Asteraceae family

Mexican Ageratum has inflorescences (flower heads) that are in clusters of lavender, blue, pink, or white depending on cultivar. Growing in a mound-like habit, flowers bloom May through October. It is considered one of the more dependable flowering annuals. Ageratum likes full sun or partial shade and in hot and dry areas, light shade is preferred. This flowering annual is best used in edging or borders of beds, and is basically free from pest and disease problems. Native to Mexico, British Honduras, and Guatemala.
