Description en: Genus of 5 or 6 species of evergreen, terrestrial perennials (bromeliads) from South America, occurring in habitats ranging from fairly dry to extremely humid, and from low terrain to mountains over 1,000m (3,000ft). They form rosettes of lance-shaped, spiny leaves and, in summer, produce showy flowers in dense, terminal, cone-like inflorescences on stout stems, giving rise to fleshy, swollen, edible fruits. In areas where temperatures fall below 15°C (59°F), grow pineapples as houseplants or in a warm greenhouse. In tropical climates, grow in a border.

Hardiness en: Frost tender.

Cultivation en:

Propagation en: Root basal offsets in early summer; or carefully sever the leafy rosette at the top of the fruit, allow it a day or two to callus, then root it in a barely moist mix of peat and sand, in indirect light at 21°C (70°F).
