Demand for varieties like Tahitian and Kaffir has built up significantly over the last few years, probably because they are so popular in Asian cooking. Limes are an excellent source of Vitamin C and provide a great substitute for lemons. They can be used for seafood dishes, chicken, meats, drinks, desserts, cakes, biscuits and marmalade.

Lime trees are frost sensitive, small and leafy, and grow to 10 feet (3 meters) with smallish, generally round yellow to green fruit at maturity. Limes have the highest requirement of all citrus varieties for heat. Tropical and subtropical areas suit them best however you can grow lime trees in cooler climates as they can tolerate light frost. Ensure they have a sheltered position, fully sunlit throughout the day and protected from cool winds.

Kaffir Lime

This lime tree is a variety grown mainly for its aromatic leaves rather than the fruit. Kaffir limes will reach 1.5 metres (5′) tall, but because the leaves are constantly being picked for cooking, the trees usually remain small in size. They have large sharp thorns and also grow well in containers. They prefer tropical conditions but can be grown in cold climates if protected from cool winds and given plenty of sunshine.

Tahitian Lime

This variety is the best lime for a cool climate. It has very few thorns and produces very juicy fruit all year round. The plants grow to around 3x3m (10×10′) tall, and they do well in the garden or in pots. The seedless fruit is small and green when ripe, although it can be left on the tree until it turns yellow. Tahitian limes are easy to grow.
