Origin: Australasia. The Latin name \'Citrus australasica\' gives away the origins of this, one of a group of citrus plants native only to Australiasia and now being increasingly marketed down under as \'gourmet bush tucker\'. Also known as the caviar lime, the finger sized fruits break open to release tiny citrus bombs that burst on the tongue. Rarely found in this country as fruit and even more rarely found as plants, with a flavour somewhere between a lime and a grapefruit, finger limes are increasingly being talked about in U.S. foodies circles as the new food delicacy. Protect from frost. Mature height 1-1.5m (3\'3-5\'). Self-fertile. Supplied in a 3 litre pot.
