Ananas: Bromeliad

Another bromeliad with certain novelty value as well as decorative qualities is the Pineapple, Ananas comosus. The wide-spreading, narrow, grey leaves form a rosette and in some forms have cream, yellow and pink stripes which add to their attractions. As these leaves can be up to 5 ft. long it goes without saying that space is necessary to accommodate this plant. Fruit may be produced if a warm, humid atmosphere is provided but this will certainly not occur under cool house conditions.

Propagation

An interesting exercise is to try to make a new plant from the spiky rosette which forms the top of a bought pineapple. This needs to be cut with a sharp knife and the flesh removed before placing it on a bed of sand in a propagating frame with a temperature of at least 24°C. (75°F.). Increase can also be by suckers, seeds and stem cuttings, again with temperatures not less that 24°C.

Cultivation

Established plants need a winter temperature of 16°C. (60°F.), in-creasing to 24°C. (75°F.) or more in summer. The atmosphere must be kept moist in spring and summer. A suitable compost consists of 2 parts fibrous loam, 1 part peat and 1 part sand. Good drainage is essential. Water freely in spring and summer when growth is active, but more moderately in winter.

Fruiting Plants

As I have already inferred, fruits are unlikely to appear under typical greenhouse conditions, but if they do, the plants must be kept rather dry while the fruits are ripening.
