Description

Haloxylon is a genus of small trees or shrubs that belong to the Amaranthaceae family. These plants are commonly known as salt bushes and are native to arid and semi-arid regions of Africa and Asia. Haloxylon species are xerophytic in nature and can survive in extremely harsh conditions, such as saline soils, high temperatures, and low rainfall.

Taxonomic Information

Appearance

Haloxylon plants are small trees or shrubs that can reach a height of up to 10 meters. They have a dense, bushy growth habit and are covered in small, scale-like leaves that are usually gray or green in color. The plants have a deep taproot system that allows them to access water from deep underground sources. Haloxylon species also produce small, inconspicuous flowers that are usually greenish or yellowish in color and are followed by small, dry fruits.

Care Guide

Haloxylon plants require very little care, as they are adapted to survive in harsh conditions. They prefer well-draining, sandy soils and should be watered sparingly, as they are drought-tolerant. Fertilization is not necessary, as these plants can obtain nutrients from the soil. Haloxylon species prefer full sun and are hardy in USDA zones 8-11.

Common Pests & Diseases
