The whole plant 10

Crown A tuft of short, stiff leaves. Cut off and planted, a crown grows into a new plant.
Fruit One fruit made of many small fruits joined together. Each small fruit grew from one flower.
Slips Slips grow on the fruit stalk, right under the fruit. Growers break them off and plant them.
Fruit stalk It grows up from the middle of the plant. It carries the fruit. Its other name is the peduncle.
Leaf The leaves grow in a spiral round the stem. Each one is long and stiff and ends in a sharp point.
Leaf spines Spines line the leaf edges on some kinds of pineapple. Other kinds have smooth edges.
Sucker A sucker grows from the stem, between the leaves. Left on the plant after the fruit is picked, it can bear the next fruit.
Ratoon It grows from the part of the stem under the soil.
Stem A pineapple stem is short and stout. The leaves grow round it in a spiral.
Roots Pineapple roots are shallow. They spread out near the top of the soil.

The fruit 4

Eyes (fruitlets) Each eye is one fruitlet, a small fruit from a single flower. All the eyes together make the pineapple.
Shell The shell is the tough outer skin, also called the rind. It turns from green toward yellow as the fruit ripens.
Flesh The flesh is juicy and can be nearly white or yellow.
Core It runs up the middle of the fruit, from stalk to crown. It is firmer than the flesh round it.

How it works

The top drawing is a pineapple plant with its fruit: leaves round a short stem, a fruit on its stalk and the young shoots that growers replant. The bottom drawing is the fruit, whole and cut in half.

Down the middle, out to the sides, then the fruit

Numbers 1 to 4 run down the middle of the plant: the crown, the fruit, the slips under it and the fruit stalk. Numbers 5 to 8 are a leaf, its spines and two more young shoots, the sucker and the ratoon. Numbers 9 and 10 are the stem and the roots. Numbers 11 to 14 are on the fruit: its eyes, shell, flesh and core.

Four parts can be planted to grow a new pineapple: the crown, a slip, a sucker or a ratoon.
A pineapple is many small fruits joined into one. Each eye grew from one flower.

Questions and answers

What are the parts of a pineapple plant?

Roots, a short thick stem, long pointed leaves, a fruit stalk, the fruit and the crown on top of it. Young shoots grow on the plant too: slips under the fruit, suckers between the leaves and ratoons from under the soil.

What are the parts of a pineapple fruit?

Outside is the tough shell, covered in eyes, with the leafy crown on top. Inside is the juicy flesh round a firmer core. Each eye is one fruitlet that grew from a single flower.

Which part of a pineapple do you plant?

Growers plant the crown from the top of the fruit, or a slip, a sucker or a ratoon taken from the plant. They use these pieces because a pineapple fruit usually has no seeds.

How many pineapples grow on one plant?

One at a time. The stem bears a single fruit at its top. After that fruit is picked, a sucker left on the plant can grow and bear the next one.
