General Information

Leucaena lanceolata is a small to medium-sized deciduous tree usually growing 5 - 15 metres tall, occasionally reaching 20 metres. The bole can be 20 - 50cm in diameter. Typically branchy when young, older trees develop a short clear bole that is unbranched for up to 5 metres, with upright angular branching and a narrow, open crown[

Cultivation Details

Leucaena lanceolala is a truly tropical species and although it is distributed as far north as Chihuahua, well north of the
Tropic of Cancer, it does not tolerate frost. Throughout its wide distribution, rainfall is highly seasonal, usually between 900 - 1,500mm, with a 3 - 6 month dry season[

Leucaena species generally require a sunny position. They are often found in the wild on poor, shallow and dry soils, usually overlying a calcareous rock. Most of them do not thrive on acid soils. Most species experience a long dry season and are more or less drought tolerant.
Leucaena lanceolata as a whole, and var lanceolata in particular, evidently thrives on disturbance and can be very common and weedy along roadsides in parts of its native range or in coastal vegetation and on dunes. Given these tendencies it poses significant risks of becoming a ruderal weed of open disturbed habitats where introduced[

]. Seedlings and direct sowing are recommended methods of propagation where soil-moisture conditions permit and economic weed control can be maintained. Seed pre-treatment involves soaking in hot water for 2 minutes or nicking the seed coat at the distal (cotyledon) end, using a sharp tool like scalpel, knife or nail clipper. A germination rate of 50-80% in 8 days can be achieved[
