The stem of pineapple is very short. There are many leaves, arranged in a rosette shape, sword-shaped, 40-90 cm long and 4-7 cm wide, with tapering tips, full or pointed teeth, green ventral surface, pink-green back, brownish red edges and tips, and the leaves born at the top of the inflorescence become smaller and often red.
The inflorescence is drawn from the leaves, like a pine cone, 6-8 cm long, and increases when it bears fruit; Bracts are green at the base, reddish at the upper part and triangular-ovate; Sepals are broadly ovoid, fleshy and reddish at the top, about 65438 0 cm long; Petals are oval, pointed, about 2 cm long, purple in the upper part and white in the lower part.
Chrysanthemum fruit is fleshy, more than15cm long. The flowering period is from summer to winter.
Pineapple has its own special growth habits. Most pineapples have rosette leaves. The base of the leaf cluster forms a leaf tube which can store water. The water needed for the growth and development of this pineapple is not stored in the mesophyll, but in the groove naturally formed at the central growth point of the clustered leaves (that is, the unique rosette-shaped leaf tube). In the growing season, we should often water the leaf tube to keep the soil moist and make the leaf tube have enough water to thrive. This is a special habit of pineapple.
Another special habit of pineapple is that it only blooms once in its life. After flowering, the mother plant will live for a period of time and then die. At this time, one or several tillers will germinate at the stem base or root of the mother plant, which is a good material for propagating new plants.
