Barrel cactus


Barrel cacti are various members of the two genera Echinocactus and Ferocactus, found in the deserts of Southwestern North America. Some of the largest specimens can be found in the Mojave Desert in southern California.

Description

Some species of barrel cactus reach over in height at maturity, and have been known to reach in some regions. The ribs are numerous and pronounced, and the spines are long and can range in color from yellow to tan to red, depending on the age of the plant and the species. Flowers appear at the top of the plant only after many years. The barrel cactus can live to be over 100 years old.
Barrel cactus buds typically start to bloom in April with a bright yellow or orange flower. Pink and red varieties also exist but occur less frequently. The flowers only appear on the very top of the plant. As the flowers begin to wilt in early May, they may change color. A late summer desert rainstorm can produce a late bloom, as shown in the photograph below of the orange flowered variety.

Fruit

As the flowers wilt away, small pineapple-shaped greenish fruit may form. Left untouched, the fruit has been known to last a full calendar year. The fruit can be easily removed but is not usually consumed because it is fairly dry and bitter.

Facts

collected the fruit as emergency food during extreme drought conditions.
The Seri people distinguished three species of barrel cactus:
In Mexico the flesh of the barrel cactus is candied and eaten as a treat.

Cultivation

Barrel cactus are cultivated by plant nurseries as an ornamental plant. They are considered easy to grow and relatively fast growing. They may produce round offshoots.
Barrel cactus can fall over because they grow based on sun orientation. They usually grow towards the south to prevent surface tissue sunburn, giving the name "compass cactus."
