Mentha arvensis 'Thai' is an exotic, wild mint with a hint of Caraway. An attractive variety with dark green leaves and distinctive dark red stems. A great mint to add to a diverse range of dishes. Its attractive lilac flowers in summer that are popular with pollinators. A delicious unmistakable mint of Thai cuisine. We love this refreshing herb in so many recipes, it is versatile and mouth-watering. Mature plants reach about 18-20 inches tall and should be spaced about 2 feet apart.
