The green tomatillo is a productive annual plant known for its abundant harvest of pale green fruits encased in delicate papery husks. Each tomatillo has a distinctive tangy, lemon-like flavor, making it an essential ingredient in traditional Mexican salsa verde. The fruit also adds a savory touch when eaten fresh in salads and omelets, or cooked in sauces and preserves. Growing on compact plants approximately 50 cm tall, the green tomatillo is ideal for container cultivation and small spaces.
