There are many wild foods available to grow and gather but sometimes it’s hard to know which ones. Some are obvious, like wild apples or berries, but can you eat a cactus?

If you live in the Southwest (or even other parts of the U.S.), you may have spotted something in the produce section called “nopales.” These are the pads of the prickly pear cactus and have been a food source to native people of the area. Looking around at all the flora in the genera, edible cactus plants make up just a fraction, but they do exist.

Are Cactus Plants Edible?

Amazingly, there are many types of edible cacti, although you may have to do some work to remove the spines. Wild gatherers may wonder, “is eating cactus dangerous?” As with any wild foraging, you must know what is safe and how to prepare your native foods.

Apparently, all the fruits of a true cactus are safe to eat, however, many need special preparation or even need to be cooked. The flavors range from fruity, sweet, and bland into the range of bitter and intolerant. Native inhabitants of cactus ranges had to figure out which were edible plants and which were best left alone.

Succulent plants like the agave have provided food from its leaves for thousands of years. Not only are they full of necessary moisture, but the leaves can be roasted for a variety of purposes. The indigenous people combined these types of plant-based food sources with hunting and cultivation to round out a balanced diet.

Is Eating Cactus Dangerous?

Most cacti species are not poisonous, but some do taste rather terrible. Harvesting any edible parts would have been strenuous and hardly worth the work for such unpleasant food sources. Several, though, are noted food stock and still used today.

In arid, warm regions there are many types of edible cacti to add to your landscape. You may find options available in Latin groceries and even specialty supermarkets. Nopales, especially, are common both fresh and canned. Even the prickly pear “tunas” (or fruits) exist in many ethnic groceries.

What Cacti to Plant for a Foraging Garden?
