Growing Notes

Easily divided in spring and moved around the garden or grown from cuttings. Not particularly invasive in California where it’s too dry down south and too cold up north. Mexican mint tends to mat on itself as it grows; a hard prune every couple years in spring refreshes your clump and keeps it tidy.

Special Interest

This plant smells convincingly of marijuana when brushed up against in the garden, always making amusing conversation during garden tours.

This Mexican mint has naturalized throughout the tropics wherever people live, evidence of its usefulness, both in the garden and kitchen. The pungent oregano-like flavor has given rise to many common names including Cuban (or Caribbean) oregano, Indian borage, and African thyme.

More Info

This plant makes an excellent houseplant. Grow it in a sunny warm room where it’ll get some direct sun.
