Billygoat weed

Hello, I’m Billygoat weed

Botanical Name

Ageratum conyzoides


I am an annual or short-lived perennial. My leaves are green, with fine hairs making me furry leaves. Billygoat weed has mauve-coloured flowers that some people find quite attractive.Through selective breeding I have also been bred into an annual that you can grow in your garden for spring and summer colour. I set lots of seeds from each flower, which I happily disperse across your garden and into your neighbours.


I grow best in dry.soils that are nutrient deficient. Correct your soils and I will no longer be a problem.


I can be controlled by hand weeding as I pull out easily, especially after rain. If you want to spray, use an organic weed killer comprised of vinegar, salt and soap or pour boiling water over me as this burns me.
