Three main types grown in Australia: Tahitian (large seedless fruit, most popular), Key/Mexican (small, aromatic, very tender), and native Australian Finger Lime (unique caviar-like vesicles, increasingly popular). Tahitian is the practical choice for most home gardens. Finger lime is a genuinely Australian native with unique culinary properties. All limes prefer warmth and humidity.
