About Billygoat weed

Ageratum conyzoides, known as 'billygoat-weed' or 'tropical whiteweed', is an annual herbaceous plant from the Asteraceae family, native to tropical America. It is characterized by its small lavender-blue or white flowers, clustered in dense inflorescences that give it a fluffy appearance. It is ideal for garden borders, pots, and as ground cover in sunny or semi-shady areas, adding a wild and delicate touch.

Native range

Tropical and subtropical America, especially Mexico and Central America

Care tips

It requires full sun or partial shade exposure for abundant flowering. Watering should be regular, keeping the substrate moist but not waterlogged, especially in warm climates. It prefers well-drained, fertile soils rich in organic matter. Avoid excessive nitrogen fertilization, as it may promote more foliage than flowers.
