Perennial. Hardy to USDA zone 5. This is the herb for cooks who don't know which herb to use. Thyme will go with almost anything! It plays a part in many French dishes and also goes great with fish, poultry, vegetables, mushrooms, omelets, quiches, soups, bean and lentil casseroles, rice, and seafood chowders just to name a few uses. With small leaves and delicate, edible flowers in early summer, this herb is a lovely 12" tall landscape plant. You can plant a hedge of thyme around your herb, vegetable, or flower garden, and grow it in containers outdoors or on a sunny windowsill.
