Opuntia is a large genus of plants native to North America and South America. All have succulent stems, some of them becoming woody with age. Stems may be cylindrical or flattened pads. Tiny, succulent leaves may be present on the newest growth (see photo below.) Most species are spiny.
Cactus Pads-also called: Nopalitos and Cactus Leaves. All opuntia species are edible (non-toxic) but some species are easier to use than others. Two parts of the plant are edible, the pads (nopalitos) and the pear (tuna).The pads are vegetable and the pear is fruit. The State of Texas named the prickly pear cactus as the state fruit/vegetable in 1995. Prickly pears are fruit from the prickly pear cactus (Opuntia sp.) and may range in color from yellow-green to deep purple-red and in colour in size from that of an apricot to 6-inches long. For this reason, there is no accurate way of judging how many pears it may take to obtain a given amount.
