Prickly Pear Cactus
Genus Opuntia

Prickly pear cactus information and care
Prickly pear cactus represent about a dozen species of the Opuntia genus (Family Cactaceae) in the North American deserts. All have flat, fleshy pads that look like large leaves. The pads are actually modified branches or stems that serve several functions -- water storage, photosynthesis and flower production. Chollas are also members of the Opuntia genus but have cylindrical, jointed stems rather than flat pads. Prickly pear cactus drink recipes
Like other cactus, most prickly pears and chollas have large spines -- actually modified leaves -- growing from tubercles -- small, wart-like projections -- on their stems. But members of the Opuntia genus are unique because of their clusters of fine, tiny, barbed spines called glochids. Found just above the cluster of regular spines, glochids are yellow or red in color and detach easily from the pads. Glochids are often difficult to see and more difficult to remove, once lodged in the skin.
The fruits of most prickly pears are edible and sold in stores under the name "tuna." Prickly pear branches (the pads) are also cooked and eaten as a vegetable. They, too, are sold in stores under the name "Nopalito." Because of the glochids, great care is required when harvesting or preparing prickly pear cactus. Both fruits and pads of the prickly pear cactus are rich in slowly absorbed soluble fibers that may help keep blood sugar stable. Prickly Pear Nectar is made with the juice and pulp of the fruits and is available from our online store. Click Here
Range & Habitat
Prickly pear cactus are found in all of the deserts of the American Southwest, with different species having adapted to different locale and elevation ranges. Most require course, well-drained soil in dry, rocky flats or slopes. But some prefer mountain pinyon/juniper forests, while others require steep, rocky slopes in mountain foothills. What is that white stuff on my cactus? The cochineal covers much of the lower elevations in the western United States and Mexico. It feeds almost solely on the pads of selected prickly pear cacti species. More information and pictures click here.
Description
Most prickly pear cactus have yellow, red or purple flowers, even among the same species. They vary in height from less than a foot (Plains, Hedgehog, Tuberous) to 6 or 7 feet (Texas, Santa Rita, Pancake). Pads can vary in width, length, shape and color. The Beavertail, Santa Rita and Blind Pear are regarded as spineless, but all have glochids.
There has been medical interest in the Prickly Pear plant. Some studies have shown that the pectin contained in the Prickly Pear pulp lowers levels of "bad" cholesterol while leaving "good" cholesterol levels unchanged. Another study found that the fibrous pectin in the fruit may lowers diabetics' need for insulin. Both fruits and pads of the prickly pear cactus are rich in slowly absorbed soluble fibers that help keep blood sugar stable. There are on going studies and at this point there are no proven results on humans. You can make your own study and see if works for you, which is the only test that really counts. More...
In addition to the North American native prickly pear cactus listed below, there are many varieties, non-native imports and hybrids, so identification can often be difficult. Information on the 15 species below is based on wild, non-cultivated samples.

The Saguaro Video
The Saguaro often begins life in the shelter of a "nurse" tree or shrub which can provide a shaded, moister habitat for the germination of life. The Saguaro grows very slowly -- perhaps an inch a year -- but to a great height, 15 to 50 feet.
Desert Food Chain Video
A food chain constitutes a complex network of organisms, from plants to animals, through which energy, derived from the sun, flows in the form of organic matter and dissipates in the form of waste heat.
