Barbed-wire Cactus. Surrounding desert prisons for years to come.

Arguably, the most common cactus to have on your office desk, never mind at home, Cereus tetragonus is a dwarf and rather tender perennial, usually potted and grown under glass. Its distinctive three or five-sided stem is mid-green in colour with fine, brown spines growing from small white, hairy tufts along its edges, thus earning it its common name, the Barbed-wire Cactus. Numerous smaller stems appear over time, while the nocturnal yellow or pink blossoms are rarely seen. Though suited to pots and containers, it grows happily in gravel beds and rockeries. Water regularly when growing, but keep dry in winter and apply low-nitrogen fertilizer for extra nourishment.
