How to Grow and Care
Zygophyllum is found in many deserts and semi-deserts of the world, including some of the aridest habitats where plant life is possible. Species are found in various habitats along hill slopes, dry rivers, ridges, road verges, coarse sandy soil, calcareous sand, and salty soil.
Species of Zygophyllum are usually not found in cultivation. However, some are very attractive with yellow, delicate petals and interesting fruits and will undoubtedly be suitable for growing in gardens.
Propagation can be done from seed or by taking cuttings in spring.
