Low mound of spiny, flat, nearly oval joints has bright yellow or sometimes bright magenta flowers. This is a small cactus whose flattened, jointed, blue-green pads lie prostrate on the ground, occasionally forming colonies several feet across. Overall height is less than 8 in.

This cactus is a nuisance on rangeland, becoming more frequent as grass is grazed away.

BenefitUse Wildlife: Many wildlife species, including pronghorn, deer, and box turtles, eat the fruits and pads.
Use Food: EDIBLE PARTS: Ripe fruit edible raw or in jelly. Leaf pads, fruit and seeds. Use tender young leaf pads gathered during the spring. PREPARATION: Wash leaf pads, fruit and seeds thoroughly with warm water. Do not use dish detergent or any type of sanitizer. These products can leave a residue. Peel and cut pulp into chunks or strips and cook like string beans. Batter, roast or fry pads. The interior of the pad similar to okra and can be used to thicken soups. Cut pads into pieces and use raw in salads. Remove bristles before use with a flame or by wiping off with a glove or damp cloth. Or, bake the pads in a medium-temperature oven for one-half hour, then peel the skin with the bristles attached. If a knife is used to cut out bristles, wipe after each cut, because mucilage produced by the pads will stick to blade. Roast the pads in their skin on a fire for about 15-20 minutes per side. Peel and eat the pulp after cooking. Peel or cut in half and scoop out pulp before use. Chill and eat raw or pickle after removing seeds. Dried seeds can be crushed or ground into flour and used in soup as a thickener. (Poisonous Plants of N.C.)
