Succulents Around the World: Where They Grow Naturally

Succulents are a global phenomenon. While cacti are native to the Americas, the broader world of succulents spans every continent except Antarctica, adapted to dry conditions from the highlands of Mexico to the rocky coasts of South Africa. Understanding where a plant comes from gives you a meaningful window into what it needs.

Africa: The Succulent Continent

Africa is home to an extraordinary diversity of succulent plants, particularly in the southern and southwestern regions. South Africa and Namibia alone contain more succulent species than anywhere else on Earth outside of the Americas.

Aloe

Aloe is native to Africa and the Arabian Peninsula, with the greatest diversity found in South Africa, Madagascar, and the Horn of Africa. Aloe vera itself is thought to be native to the Arabian Peninsula or northeastern Africa. In their natural habitat, aloes grow in open, rocky terrain with excellent drainage, often in full sun. They are adapted to survive prolonged dry seasons and periodic intense rain.

Haworthia and Gasteria

Both haworthia and gasteria are native to South Africa, where they grow in rocky, shaded environments under shrubs or in the crevices of rocks. This origin explains why they tolerate lower light levels than most other succulents. They evolved in dappled shade, not full sun.

Euphorbia

Many succulent euphorbias are native to Africa and Madagascar, where they fill the ecological role that cacti fill in the Americas. They evolved independently but ended up looking remarkably similar, a convergent evolution driven by the same dry conditions.

Mexico and Central America: Echeveria Country

Mexico is the center of diversity for echeveria, which is why so many echeveria species have such visually striking, tightly packed rosettes. They evolved at high altitudes in rocky, well-draining soils where temperatures can swing widely between day and night. This background explains their preference for bright light and their sensitivity to prolonged moisture in the soil.

The Arabian Peninsula and the Mediterranean

The Arabian Peninsula is home to aloe vera and several other succulents adapted to extreme heat and drought. The Mediterranean basin hosts its own range of drought-adapted plants, including sedums and sempervivum, which evolved in the rocky, thin soils of mountain regions across Europe and Asia Minor.

What This Means for Growing Them

A plant's native climate is its care manual in shorthand. Haworthia grown in the crevices of South African rocks tells you it wants shade and a gritty, fast-draining substrate. Echeveria growing on a Mexican hillside at altitude tells you it wants bright sun, cool nights, and dry soil between waterings. Aloe growing in open African scrub tells you it wants full sun and can handle heat but not sustained cold and wet together.
