Description

Fruits of guanacaste

The guanacaste is a large tree, growing to 20–30 m (66–98 ft) tall, with a trunk up to 3 m (9.8 ft) in diameter. The bark is light gray. The crown (the upper part of tree) is broad and widely spreading. Leaves are 15 to 50 cm (5.9 to 19.7 in) long, alternate and compound.

The guanacaste is evergreen, or briefly deciduous for 1–2 months during the dry season (without rains). Most leaves fall in December, at the start of the dry season. In late February, leaves start to appear and produce a fresh, thick crown by April.

Flowers are hermaphrodite; the pollination is by insects like bees.

The fruit is a legume (also known as a pod) with the shape of a human ear.

Where it grows

The guanacaste tree is native to tropical America. It grows from southern Mexico through Central America to northern South America. It is found also in the West Indies. It has been introduced in other tropical regions.

It grows normally at an elevation from sea level to 500 m (1,600 ft), usually along the coast and rivers.

Uses

The wood is reddish-brown, lightweight and water-resistant; it is used to make objects like doors, windows, furniture, cabinets, and for shipbuilding. It is used also as firewood.
