Description: A small much branched evergreen tree. It<br />

grows up to 5-6 m tall with short sharp spines. It<br />

spreads to 3 m across. The leaves are small and dark<br />

green. There are narrow wings on the leaf stalk. The<br />

leaf blade is about 5 cm long by 3 cm wide and oval.<br />

They have a sweet smell when crushed. There is a<br />

thorn at the base of each leaf. (Thorn free kinds are<br />

known). The flowers are yellowish white. They are<br />

2.5 cm across and have 5 petals. The flowers are<br />

produced in the leaf axils or at the ends of branches.<br />

The fruit is small, round 3-4 cm across and become<br />

pale orange to yellow when ripe. They are thin<br />

skinned. The flesh of the fruit is green. West Indian<br />

limes with larger, better fruit also occur<br />

Distribution: They need a warm climate and are most common in coastal regions in the lowland<br />

tropics. They grow from sea level to 2200 m altitude in Papua New Guinea. They suit humid<br />

areas and can survive in poor soils. Light to medium well drained soils are best. It is drought<br />

and frost tender. It grows in Nepal to about 1800 m altitude. It can grow in alkaline soil. It suits<br />

hardiness zones 11-12.<br />

Cultivation: They are often grown from seed but are better if grafted. <strong>Plants</strong> can be grown by<br />

cuttings. A spacing of 4-5 metres is suitable. When grown from seed, several shoots may<br />

develop from the one seed, which means the seedlings may be identical to the parent.<br />

Production: Trees can start producing fruit quickly. They fruit in 5-6 years. They normally<br />

produce fruit all the year round. Fruit drop when mature. Black limes are sun dried limes. They<br />

are 2.5-4 cm across.<br />
