Distinctive Features and Uses

Fruits: Key Limes are small, usually around 1-2 inches in diameter, with a thin, smooth, greenish-yellow skin when ripe. The flesh is pale green and packed with juice, offering a sharp, tangy flavor that is more intense than that of the common Persian lime. The fruit is typically used when fully ripe and yellow but can also be harvested green for a more acidic taste. Key Limes are perfect for use in pies, marinades, cocktails, and any dish that benefits from a zesty citrus kick.

Leaves: The tree has glossy, dark green leaves that are aromatic when crushed, adding to the overall sensory appeal of the plant.

Growth Habit: Key Lime trees are relatively small, usually growing to about 6-10 feet tall, making them ideal for container growing or small gardens. They are evergreen and can produce fruit year-round in warm climates.
