Key lime is a famous species of lime (Citrus aurantifolia) that is also known as Mexican lime or West Indian lime. The fruit is sweeter than the Persian lime and is well-known as the base ingredient in a key lime pie.
Key lime trees need rich, well-draining soil that is kept consistently moist. The leaves are glossy deep green, oval in shape. The fragrant flowers precede small green fruit, about the size of a golf ball. The fruits are usually picked while they are green, but they will ripen to a yellow color. (source: The Spruce)
