A pungent, easy-to-grow Mexican herb traditionally cooked with beans for its distinctive, resinous flavor. It grows fast and self-seeds freely once established, behaving almost like a weed in warm gardens. The one rule: cut off flower heads before they set seed, or it will spread everywhere.
Its strong scent is thought to help deter flea beetles and cabbage pests, but keep it away from small seedlings — its compounds can slow their early growth.
