#Ageratum

• Ageratum — A genus of annual or perennial herbaceous plants in the family Asteraceae, native to tropical regions of the Americas, widely cultivated as ornamental plants. Characterized by dense, globular inflorescences of blue, violet, or white color, these plants possess the trait of retaining their flower freshness for a long period.
• Ageratum conyzoides — A species of annual herbaceous plant in the genus Ageratum, native to tropical America, widely distributed as an invasive weed in warm regions of the world and recognized for its medicinal properties. Its leaves emit a strong, goat-like odor, and it is traditionally used for its anti-inflammatory, analgesic, and wound-healing effects, although it contains pyrrolizidine alkaloids toxic to the liver.
• Ageratum corymbosum — A species of perennial herbaceous plant in the genus Ageratum, native to Mexico and the southern United States, characterized by corymbose inflorescences made of small, deep-blue or violet flowers. It is occasionally used in horticulture for its ability to attract pollinators and its superior resistance in arid climates compared to annual species.
• Ageratum houstonianum — A species of annual herbaceous plant in the genus Ageratum, native to Central America and Mexico, widely cultivated globally as an ornamental border plant. It is noted for its compact mounds and dense capituliform inflorescences, with the flower heads resembling blue, lavender, pink, or white floss-like tufts, highly valued in urban landscape design.
