Citrus australasica 'Green Sapphire' (Green Sapphire Finger Lime) is a premium cultivar of Australian native finger lime, celebrated for its attractive, dark green, sausage-shaped fruits and exquisite lime-flavoured caviar. This variety produces particularly dense foliage on a moderately thorny, bushy shrub, offering both ornamental appeal and high fruit yield. The fruit's interior is filled with vibrant green, pearl-like vesicles that provide a burst of tangy flavour, making them a favourite for gourmet cuisine, cocktails, and garnishes.
Ideal for home gardens, containers, and commercial cultivation, 'Green Sapphire' thrives in well-drained soil and full sun to partial shade. It is well-suited to subtropical and temperate climates and shows good resistance to common citrus pests and diseases. This finger lime is especially valued for its consistent fruit quality, striking green caviar, and versatility in both sweet and savoury dishes.
