Mexican tarragon is considered safe for culinary use, but like other marigolds, it has mild toxicity. It can cause skin irritation in sensitive individuals and digestive upset if consumed in large quantities, so it’s best used in moderation.
Overview
Mexican tarragon (Tagetes lucida) is a tender perennial often grown as an annual. It is part of the marigold family and produces a distinct anise-like flavor similar to culinary tarragon. Mexican tarragon is one of the best substitutes for French tarragon in warm climates. It grows easily from seed, thrives in heat, and produces a strong, reliable flavor.
