Goatweed (Ageratum conyzoides)

Ageratum conyzoides (tropical whiteweed or goatweed) is a fast-growing, annual or short-lived perennial herb native to tropical America but now widespread in Asia, Africa, and Oceania. It features soft, hairy stems, green leaves, and clusters of small, fluffy flowers that are usually white to pale blue or purple. Commonly found in disturbed soils, roadsides, and gardens, it is considered a weed in many regions. The plant has traditional medicinal uses, including anti-inflammatory and wound-healing properties, and also serves as a nectar source for pollinators.
