Opuntia ammophila Opuntia ammophila Opuntia ammophila, the devil's-tongue, is a species of prickly pear cactus in Florida. Individuals typically occur singly and do not generally form dense thickets. "O. ammophila" was once considered a variety of "O. humifusa"; however, it is a distinct species. Among their many differences, "O. ammophila" has gray-green cladodes rather than green or grass-green. "Opuntia ammophila" can grow to the height of humans, and large plants with thick trunks were encountered 100 years ago. However, now it is unusual to find plants that are even 1 m tall. However, even small plants form a single trunk. The flower
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
