Growing notes
- Plant in herb borders and kitchen gardens for the upright tufted habit and bright yellow autumn flowers
- Edible leaves — strong anise flavour, used as a substitute for French tarragon (Artemisia dracunculus, already in the database) in climates too hot or humid for the real thing
- Distinct from French marigold (Tagetes patula) and Aztec marigold (T. erecta) already in the database — Mexican tarragon is grown for the foliage flavour rather than for the flowers
- Frost-tender — perennial only in mild-winter climates, grown as annual elsewhere
Pet caution: Mexican tarragon (Winter tarragon) is listed as potentially harmful to cats and/or dogs. Keep pets from grazing on it, and contact a vet if you suspect your animal has eaten some.
