The Mexican lime tree, also known as the Key lime or Citrus aurantifolia, is a small and bushy citrus tree that produces fruit known for its distinctively tart and acidic flavor. It is native to Mexico and is widely cultivated in tropical and subtropical regions around the world.
 
The Mexican lime tree typically grows to a height of about 6 to 13 feet with dense, glossy green leaves and thorny branches. The fruit of the Mexican lime tree is small, round, and yellowish-green when mature. The thin skin of the fruit is smooth and fragrant.
 
When sliced open, the fruit reveals juicy, pale green flesh that is highly acidic and intensely aromatic. Mexican limes are known for their tart and tangy flavor, which adds a refreshing and zesty kick to a variety of dishes and beverages. They have a distinct flavor profile that is widely used in culinary applications, especially in Mexican and Caribbean cuisine.
 
The Mexican lime tree is valued for its productivity and the quality of its fruit. It is a popular choice for home gardens and commercial plantations, as it produces abundant crops of small, flavorful limes. Mexican limes are commonly used in cooking, baking, cocktails, marinades, dressings, and the famous Key lime pie.
 
Mexican lime trees thrive in warm climates and prefer well-drained soil and full sun exposure. They are relatively small in size, making them suitable for container planting as well. The tree's attractive foliage, fragrant flowers, and the tangy fruit it produces make the Mexican lime tree a desirable addition to citrus orchards and home gardens alike.
