Barrel Cactus Genus

Genus Ferocactus

barrel cactus with flowers

Ferocactus, meaning "fierce or wild cactus,"are always cylindrical or barrel shaped and are usually among the largest cacti of the North American deserts. All members of this genus have prominent ribs and are fiercely armed with heavy spines. In some species, one or more central spines are curved like a fishhook, accounting for the common name Fishhook Barrel Cactus.

Barrel Cactus flowers always grow at the top of the plant. They bear no spines and only a few scales. Fruits become fleshy and often juicy when mature, but are not usually considered edible.

Native Americans boiled young flowers in water to eat like cabbage and mashed older boiled flowers for a drink. They also used the cactus as a cooking pot by cutting off the top, scooping out the pulp and inserting hot stones together with food. The spines were used as needles, awls and in tattooing.

The pulp of barrel cactus has been widely used for making cactus candy (thus one of its common names, Candy Barrel Cactus), but this has also accounted for its destruction and, therefore, protected status in many areas.

In an emergency, the pulp of the stem can be chewed for its food and water content, but obvious care must be taken during such an operation. The taste can vary greatly depending on species.

Natives refer to all species of Barrel Cactus as Biznaga, Bisnaga and Viznaga. There are a number of species of this genus, most of which grow in central Mexico and Baja, California. Four species are recognized growing in the deserts of the American Southwest.

Growing up to 10 feet high, all have stout ribs, Dense clusters of spines usually grow along the ribs, sometimes forming a cross in the center of the cluster.

The Bobcat

The BobcatVideo available on this subject.
Despite its pussycat appearance when seen in repose, the bobcat is quite fierce and is equipped to kill animals as large as deer. However, food habit studies have shown bobcats subsist on a diet of rabbits, ground squirrels, mice, pocket gophers and wood rats. Join us as we watch this sleepy bobcat show his teeth.
