Ephedra is a genus of about 74 species of leafless-looking, green-stemmed desert shrubs (jointfirs, Mormon tea) native to dry regions worldwide. Their photosynthetic green stems and tiny scale leaves let them thrive in full sun and sandy, well-drained, arid conditions.

Family
Ephedraceae (Ephedr family)
Light
Full sun
Water
Water sparingly and let the soil dry out fully between waterings; drought tolerant once established.
Soil
Sandy or gritty, very well-drained soil or mineral mix.
Temperature
Tolerates a wide range; many species are cold-hardy, but protect tender species below about -5 °C.
How easy
Easy
Safety
Toxic: Stems and other parts of some species contain ephedrine-type alkaloids (the source of the stimulant ephedra/ma huang), which can cause dangerous cardiovascular and nervous system effects if ingested.

About

Ephedra is a genus of gymnosperm shrubs. As of July 2025, 74 species, and two hybrids, are accepted. The species of Ephedra are widespread in many arid regions of the world, ranging across southwestern North America, southern Europe, northern Africa, southwest and central Asia, northern China, and western South America. It is the only extant genus in its family, Ephedraceae, and order, Ephedrales, and one of the three extant genera of the division Gnetophyta together with Gnetum and Welwitschia.

In temperate climates, most Ephedra species grow on shores or in sandy soils with direct sun exposure. Common names in English include joint-pine, jointfir, Mormon-tea, or Brigham tea. The Chinese name for Ephedra species is mahuang (simplified Chinese: 麻黄; traditional Chinese: 麻黃; pinyin: máhuáng; Wade–Giles: ma-huang; lit. 'hemp yellow').

Where it grows

The genus is found in dry and desert regions worldwide, except for Australia.
