Taxonomic Information

Appearance

Ephedrales are shrubs that can range in size from small and spreading to large and upright. They have slender, green or gray-green branches that are jointed and segmented. The leaves of Ephedrales are reduced to scales or small, needle-like structures that are arranged in whorls around the branches. These plants are dioecious, meaning they have separate male and female plants. The flowers of Ephedrales are small, inconspicuous, and lack petals. The seeds are enclosed in a fleshy, brightly colored structure called an aril.

Care Guide

Ephedrales are hardy plants that require little care. They are drought-tolerant and can survive in poor soils. However, they do require adequate sunlight and well-drained soil. These plants should be watered regularly during their growing season and should be fertilized with a balanced, slow-release fertilizer. Ephedrales are hardy in zones 4-10.

Common Pests & Diseases

Ephedrales are generally resistant to pests and diseases, but they can be affected by spider mites, aphids, and scale insects. These pests can be controlled with insecticidal soap or neem oil. Root rot can be a problem in poorly drained soils, so it is important to ensure that the soil is well-drained.

Habitat

Ephedrales are found in arid and semi-arid regions around the world, including North America, Europe, Asia, and Africa. They are typically found in desert or steppe environments and can grow in a variety of soils, including sandy, rocky, and clay soils.
