About French Tarragon

French tarragon is the gourmet herb of classic French cuisine — anise-scented leaves that elevate chicken, fish, and béarnaise sauce. A perennial that comes back reliably each spring.

Buy transplants (true French tarragon does not grow true from seed — Russian tarragon is inferior). Plant in well-drained soil — root rot is the main killer. Divide every 3-4 years to maintain vigor. Cut back to 2 inches in fall.
