Most citrus trees are grown for what you squeeze out of the fruit. The Makrut Lime is the rare exception — it's prized almost entirely for its aromatic leaves and knobbly, deeply wrinkled rind.
The leaves are unmistakable: glossy, dark green, and shaped like a double hourglass, with one leaf appearing to grow out of the tip of another. Torn or bruised, they release a bright, floral citrus perfume with no real substitute, which is exactly why they're indispensable in tom yum, green and red curries, and countless Thai, Lao, Cambodian, and Indonesian dishes.
Frost-tender and happiest in warmth, the Makrut Lime is the tree that turns a windowsill or patio into a working spice garden — grown outdoors in warm regions, or in a container that summers outside and overwinters indoors where it's cold. It earns its place not at harvest, but every single time you cook.
Best suited to USDA zones 10 through 12 and intolerant of frost. In colder climates, grow it in a container and bring it indoors before temperatures drop. Plant in full sun in well-drained soil and water moderately.
Please note: This tree ships in a citra pot—a tall, narrow container that promotes vertical root growth and prevents root circling.
