Ponderosa lemon is a large citrus fruit-producing tree known for its enormous, uniquely textured lemons. The fruits have a thick, bumpy rind and can weigh up to 2 pounds (0.9 kg). The tree, a hybrid between a lemon and a citron, grows up to 12-24 feet (3.7-7.3 meters) tall.

Ponderosa lemon trees prefer USDA hardiness zones 9-11 and require full sun, well-draining soil, and consistent watering. They are sensitive to cold temperatures and may need protection from frost in cooler climates.

Fruit production occurs year-round, with the heaviest harvests in winter and spring. Ponderosa lemons have a tart, tangy flavor and are versatile in culinary applications, such as cooking, baking, and making beverages.
