About

Nitraria retusa, commonly known as nitre bush, is a salt-tolerant and drought-resistant shrub in the family Nitrariaceae. It can grow to heights of 2.5 metres (8 ft 2 in), although it rarely exceeds more than 1 m in height. It produces white/green coloured flowers and small red fruit.

The plant is native to desert areas of northern Africa, where it grows in primary succession on barren sand dunes. It also grows in areas with high salinity such as salt marshes.

Where it grows

This plant is native to North and East Africa, the Arabian Peninsula and the Middle East. It typically grows in salt marshes and semi-arid saline areas of deserts and it can help in the stabilisation of loose soils. It grows in primary succession on barren sand dunes.

Uses

The fruit turns red as it ripens and is enjoyed by humans. Camels and goats feed on the succulent leaves of this plant and desert-dwellers have used it as a source of salt. The wood is used for fuel and the fruits are sometimes used to make an intoxicating drink.
