Citrus hystrix, commonly known as Kaffir Lime or Makrut Lime, is an evergreen tree native to tropical Southeast Asian regions such as Indonesia, Thailand, and Malaysia. It typically grows to a height of 7 to 36 feet tall and is characterized by its glossy, dark green, hourglass-shaped leaves which are highly aromatic. The tree produces small, white or pale pink flowers that bloom sporadically throughout the year, leading to the development of distinctive bumpy green fruits that ripen to a yellow color. The fruit is relatively small, with a diameter of 2 to 3 inches.

The leaves of the Makrut Lime are widely used in Southeast Asian cuisines to impart a strong citrus fragrance to dishes, and the zest is often incorporated into curry pastes. Beyond its culinary uses, the fruit’s juice has applications in traditional medicine and is used as a cleanser in Thailand. Makrut Lime oil, extracted from the rind, is valued in aromatherapy and the production of various cosmetic products. The tree is well-suited for container gardens and patios, and it can be a focal point in tropical-themed gardens. In cultivation, it requires full sun to part shade, consistent moisture, and well-draining soil. It is sensitive to cold and must be protected from frost. While generally pest-resistant, it can be susceptible to citrus canker and citrus greening disease, which can be mitigated with proper care and monitoring.CC BY-SA 4.0
