Growing Blue Horizon Ageratum Flower Garden Seeds

Ageratum houstonianum, or sometimes called Mexican Paintbrush, is a flower native to Guatemala, Belize, and intermittently throughout Mexico, but has since naturalized to similar tropical regions in surrounding countries. Ageratum houstonianum is known to be toxic to grazing animals and, if grown beyond its natural habitat, may spread invasively. The genus Ageratum is loosely translated from Greek meaning "does not age" in reference to the long-lasting color well into the season.
