History & Origins

Christopher Columbus brought cucumber seeds to Haiti in 1494, helping these cool vegetables spread to North America!

Science & Making

Cucumbers are actually fruits, not vegetables, because they have seeds inside and grow from flowers!

A cucumber plant can climb up to 6 feet high using tiny spiral tendrils that work like nature's velcro!

One cucumber plant can grow lots of cucumbers — usually 10 to 20 per season, and sometimes 30 to 50 when it's very well cared for.

Cucumbers are almost all water — about 95 to 96%. That’s why they feel so cool and refreshing on a hot summer day!

A cucumber grows from a tiny seed into a ready-to-eat vegetable in about 7 to 10 weeks — usually around 50 to 70 days!

Cucumber plants have both boy and girl flowers on the same plant – only the girl flowers make cucumbers!

Cucumber plants make special chemicals that make them taste bitter to protect themselves from being eaten by animals!

Cucumbers, watermelons, pumpkins, and squash all belong to the same plant family, called Cucurbitaceae (also known as the gourd family).

Ingredients & Nutrition

A cucumber is very low in calories — about 8 calories for a small serving — and because it’s nearly all water (about 95–96%), it helps you stay refreshed and hydrated when you eat it.

Cucumbers contain vitamin K, which helps your bones grow strong and healthy!

The skin of a cucumber contains most of its nutrients, including fiber that helps your tummy feel happy!

Cucumbers are super refreshing and full of water — but they don’t give you much energy. If you want a real energy boost, a banana is much stronger than a cucumber.

Cucumber slices feel cool and refreshing — and because cucumbers are mostly water and have gentle skin‑soothing stuff in them, putting chilled slices on tired eyes can help calm swelling and make puffy eyes look smaller for a little while.

Eating a whole medium cucumber gives you about 40% of the vitamin K your body needs each day.

Cucumbers contain antioxidants that work like tiny superheroes protecting your body's cells!

The wax coating on store-bought cucumbers is natural and safe to eat – it helps keep them fresh longer!

Fresh cucumbers usually have more vitamins, like vitamin C and potassium, than pickled cucumbers, because pickling can lower some nutrients.

One cucumber is mostly water — and it can give you several small drinks’ worth of water! A medium cucumber has around 280–300 ml of water, which is enough to fill many shot glasses.
