''Fouquieria splendens'' (commonly known as ocotillo , but also referred to as coachwhip, candlewood, slimwood, desert coral, Jacob's staff, Jacob cactus, and vine cactus) is a plant indigenous to the Sonoran Desert and Chihuahuan Desert in the Southwestern United States (southern California, southern Nevada, Arizona, New Mexico, western Texas), and northern Mexico (as far south as Hidalgo and Guerrero).〔(Biota of North America Program 2014 county distribution map )〕〔McVaugh, R. 2001. Ochnaceae to Loasaceae. 3: 9–751. In R. McVaugh (ed.) Flora Novo-Galiciana. The University of Michigan, Ann Arbor〕 Ocotillo is not a true cactus. For much of the year, the plant appears to be an arrangement of large spiny dead sticks, although closer examination reveals that the stems are partly green. With rainfall, the plant quickly becomes lush with small (2–4 cm), ovate leaves, which may remain for weeks or even months. Individual stems may reach a diameter of 5 cm at the base, and the plant may grow to a height of 10 m (33 ft). The plant branches very heavily at its base, but above that, the branches are pole-like and only infrequently divide further, and specimens in cultivation may not exhibit any secondary branches. The leaf stalks harden into blunt spines, and new leaves sprout from the base of the spine. The bright crimson flowers appear especially after rainfall in spring, summer, and occasionally fall. Flowers are clustered indeterminately at the tips of each mature stem. Individual flowers are mildly zygomorphic and are pollinated by hummingbirds and native carpenter bees. ==Cultivation== Planting ocotillo can be done the year around with care. Ideal ocotillo plants have been grown from stem cuttings or from seed. Transplanting large bare-root plants has marginal success. They should be planted to the original growing depth and, as with cacti, in their original directional orientation. The original south side of the plant, which has become more heat and sunlight-resistant, should again face the brighter, hotter southern direction. If their direction is not marked, success is again limited. Ocotillo plants prefer well-drained, sandy or gravely loam soils with light to moderate amounts of organic content. Sunny, open, unrestricted locations and those where surface water does not collect are ideal for ocotillo. Transplanted ocotillo plants require irrigation to become established, but once established, they can survive on 8 inches of rainfall per year. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Fouquieria splendens」の詳細全文を読む スポンサード リンク
