Here's what 13 of your favorite foods look like before they're harvested

You may have thought pineapples grew on trees, but they actually live on bushes until it's harvesting time.

Here's a whole field of pineapple plants, each with their own fruit.

Asparagus grows from a bulb that's planted in a field.

Here's a bunch that's been uprooted and is ready for eating (after it's trimmed and cleaned).

These fuzzy little pods are unripe almonds.

The green pods eventually dry out and crack open on the tree branch, revealing the almond nut inside.

Almonds are instantly recognizable once they've been shelled.

Another popular tree nut is the pistachio. These pink blooms will soon give way to the notoriously tough shell.

You can still see traces of the pinkish-red bloom on the meat of the pistachio after it has been picked and dried.

Another bizarre tree nut is the cashew. The actual nut grows on the bottom of a fruit, called the "cashew apple."

Cashews are removed from their fruit for the harvest. The "cashew apple" is often juiced and sold in concentrated form.

This is a peanut field. Peanuts are legumes, which means they're different from their tree-nut friends.

The part of the peanut we eat is the plants' seed — which is uncovered once you dig up the plant.

It can take up to 160 days for peanuts to grow underground before they're ready for eating.

Let's take a look at some spices now. Ever wonder why saffron is so expensive? That's because it's harvested from the center of crocus flowers.

Saffron threads are really the stigma part of the flower, and need to be handled delicately during the picking process.

Saffron is usually sold by weight, with just a few threads packaged into glass bottles.

This vine plant looks almost exactly like wild string beans ...

... but it's really a fresh vanilla orchid plant. The green pods are harvested and then dried out.

Vanilla bean pods are dried until brown, and the sliced open and scraped to reveal the vanilla "paste" inside (which is really just a ton of little seeds).

This is what a sesame plant looks like.

The little pods hold sesame seeds (either black or white) which are harvested and used whole or processed into sesame oil.

One of the most common spices is pepper — which grows in little berry clusters on these plants.

Here's a closer look at fresh pepper.

Depending on which species of the pepper plant is growing, the berries can be red or green.

The individual berries are picked and dried out to make peppercorns.

This one may have been obvious, but did you know that cinnamon sticks are just dried tree bark?

This is a close-up look at the trunk of a cinnamon tree, where the bark has been shaved into sticks.

When you see a ton of cinnamon together, it just looks like wood shavings.

Another funny tree fruit is the kiwi. These little green fruits aren't ripe yet, hence their extreme green coloring.

The kiwi trees resemble grape vines, with dozens of fruits hanging from their branches.
