Plant Details

Native to South America, this familiar bromeliad is known botanically as Ananas comosus. Reaches 23 ft. tall, 12 ft. wide, with a short, thick stem topped by a rosette of long (1- to 6-ft.), narrow, dark green leaves with saw-toothed edges. At bloom time, the stem lengthens and produces a head of small red or purple flowers, which eventually develops into the pineapple fruit. Fruit is typically borne one per stem.

To grow pineapple, cut the leafy top from a market pineapple (cut about an inch below the leaves). Root in water or fast-draining but moisture-retentive potting mix. When roots have formed, move pineapple to an 8-in. pot of rich soil. Plant will overwinter only in the Tropical South (USDA 10-11); elsewhere, grow it as a full-time houseplant or move it indoors in winter. Water when soil goes dry; feed every three or four weeks with a general-purpose liquid houseplant fertilizer. If you're lucky, fruit will form in about two years, but it will be much smaller than a typical market pineapple.

'Variegatus', with pink, white, and olive-green leaves, is sometimes sold as a houseplant; it can take reduced light, since it is grown for foliage rather than fruit. It will fruit outside, however.
