Key Lime Tree (Mexican Lime)
Citrus × aurantiifolia
Description
Small fruit, big flavor—Key Lime is the citrus tree behind that unmistakable tart, aromatic punch. Known as the “bartender’s lime,” this compact evergreen produces an abundance of small, thin-skinned limes packed with bold, tangy juice perfect for pies, cocktails, marinades, and more.
With fragrant white blooms and glossy green foliage, this tree is as ornamental as it is productive. Whether grown in a container on the patio or planted in warm climates, Key Lime delivers year-round interest and harvests.
