原生地・分布（英語）: New World
説明（英語）: Genus of about 200 species of perennial cacti, ranging from alpine and ground-cover plants to bushy and tree-like species, from often very arid regions in North, Central, and South America, and the West Indies. They have usually pad-like and flattened, or sometimes cylindrical, club-shaped, or spherical, segmented branches, with areoles producing spines and glochids (barbed spines); a few species have leaf-like scales, which soon fall. On mature plants, funnel- or bowl-shaped flowers are produced singly from the areoles at the tips or sides of the segments; they appear during the day in spring or summer, and are followed by usually spiny, obovoid or spherical fruits (prickly pears). In a few species, these are edible, and contain large, smooth white seeds in pulp. Where temperatures drop below 10°C (50°F), grow tender species in a cool or temperate greenhouse. In warmer areas, grow opuntias in a desert garden or in a border with other cacti. They are not suitable as houseplants; contact with the bristles causes intense irritation to skin, and they are difficult to remove.
耐寒性（英語）: Fully hardy to frost tender.

繁殖（英語）: Sow pre-soaked seed at 21°C (70°F) in spring. Separate and root stem segments. Handle plants using folded newspaper; dispose of it after use.
