Pineapple


The pineapple is a tropical plant. It is delicious to eat in fruit salads and desserts. According to Wikipedia, the pineapple (Ananas comosus) is probably native to Uruguay, Brazil or Paraguay. It is a medium tall (1–1.5 m) herbaceous perennial plant with 30 or more trough-shaped and pointed leaves 30–100 cm long, surrounding a thick stem.

The pineapple is an example of a multiple fruit: multiple, spirally-arranged flowers along the axis each produce a fleshy fruit that becomes pressed against the fruits of adjacent flowers, forming what appears to be a single fleshy fruit. The leaves of the cultivar 'Smooth Cayenne' mostly lack spines except at the leaf tip, but the cultivars 'Spanish' and 'Queen' have large spines along the leaf margins. Pineapples are the only bromeliad fruit in widespread cultivation. Go here to learn more about this citrus plant.
