The genus Pineapple (Ananas) unites 5 species of evergreen plants, some of them have edible fruit trees. In natural conditions , they are one of the few bromeliads that are not epiphytes (they use other species as a support) and therefore have a normal root system.
These are perennial herbaceous plants up to 1 m high with a strongly shortened stem and a characteristic rosette of hard, curved, prickly leaves along the edge, from the center of which peduncles develop. The fruit stock is orange-brown, large, and very decorative. Fruiting is possible only in heated greenhouses.
The most well-known species cultivated in rooms is the crested pineapple (Ananas comosus, or A. sativus) with belt-shaped bluish-green pointed leaves. The peduncle is short and strong, with small purple bract leaves at the top and bright blue flowers. A very common variegated form with leaves outlined with a whitish-cream border. During the flowering period, all the Central leaves (if only the place was in the open sun) become bright pink. The variety 'Porteous' sheets with longitudinal yellowish cream stripes, sometimes on the edge of the red.
Pineapple bract (A. bracteatus) has lilac - purple flowers, which in natural conditions are replaced by large edible chestnut fruit trees. For decorative purposes, the Tricolor variety is grown, among others, with leaves that have a yellowish-cream border and reddish spines.
