Zygophyllales
Contents
Description
Zygophyllales is an order of flowering plants, commonly found in arid regions of the world. The order comprises of around 30 genera and over 300 species, including some of the most hardy and drought-tolerant plants on the planet. The name ‘Zygophyllales’ is derived from the Greek words ‘zygon’ (meaning yoke) and ‘phyllon’ (meaning leaf), referring to the paired leaflets on the plant’s compound leaves.

Appearance
Zygophyllales plants are known for their unique appearance, which helps them to survive in harsh desert conditions. Most species have small, thick leaves that conserve water, and many have spines or thorns to deter herbivores. Their flowers are often small and inconspicuous, but can be quite showy in some species.
Care Guide
Zygophyllales plants are generally quite hardy and low-maintenance, making them a good choice for gardeners in arid regions. Here are some tips for caring for these plants:- Water: Most Zygophyllales plants are drought-tolerant and don’t require much water. However, they may benefit from occasional deep watering during hot, dry periods.- Fertilization: These plants don’t typically require much fertilizer, but you can apply a slow-release, low-nitrogen fertilizer in the spring if desired.- Soil: Zygophyllales plants prefer well-draining soil, as they are susceptible to root rot in poorly-draining soil. Adding some sand or gravel to the soil can help improve drainage.- Sunlight: These plants generally prefer full sun, although some species can tolerate light shade.- Hardiness Zones: Most Zygophyllales plants are hardy in USDA zones 9-11, although some species can tolerate colder temperatures.
Common Pests & Diseases
Zygophyllales plants are generally quite resistant to pests and diseases, but they can still be affected by a few common issues. Some potential pests and diseases to look out for include:- Spider mites: These tiny pests can cause yellowing and wilting of the leaves. They can be treated with insecticidal soap.- Root rot: Overwatering or poorly-draining soil can lead to root rot in Zygophyllales plants. To prevent this, make sure the soil is well-draining and avoid overwatering.
Habitat
Zygophyllales plants are primarily found in arid or semi-arid regions, where they have adapted to survive in extremely dry conditions. They are found in a wide range of habitats, from deserts and scrublands to rocky slopes and coastal areas. Some common genera in this order include Tribulus, Guaiacum, and Zygophyllum.
