Opuntia humifusa Those recognizing this species treat "Opuntia rafinesquii" as a junior synonym. This plant is very intolerant of shade. It thrives in full sun in hot and dry environments and needs well-drained soil. Opuntia humifusa will grow in open or exposed areas in rocky and coastal scrub habits as well as at elevations where winter hardy. Opuntia humifusa Opuntia humifusa, commonly known as the devil's-tongue, eastern prickly pear or Indian fig, is a cactus native to parts of eastern North America. As is the case in other "Opuntia" species, the green stems of this low-growing perennial cactus are flattened, and are
Opuntia ficus-indica the Mediterranean basin. Under those hedges and adjacent areas soil physical properties, nitrogen and organic matter are considerably improved. Structural stability of the soil is enhanced, runoff and erosion are reduced, while water storage capacity and permeability is enhanced. Prickly pear plantations also have a positive impact on plant growth of other species by improving severe environmental conditions which facilitate colonization and development of herbaceous species. Opuntia ficus-indica is being advantageously used in Tunisia and Algeria to slow and direct sand movement and enhance the restoration of vegetative cover, minimizing deterioration of built terraces with its deep and strong rooting
