Pumpkin

A pumpkin is a winter squash

“Pumpkin” is more cultural label than botanical category. It’s used for several round, orange winter squash species:

• Cucurbita pepo — the field pumpkin, the carving pumpkin, and zucchini.
• Cucurbita moschata — butternut squash, calabaza, sugar pumpkin (often used for pies).
• Cucurbita maxima — Hubbard, kabocha, and the giant prize-winning pumpkins.

The same vegetable might be called “pumpkin” in one country and “squash” in another. Australians use “pumpkin” for what Americans call butternut squash; Americans reserve “pumpkin” for the orange kind.

The pie pumpkin lie

Most American “pumpkin pie” — including most canned pumpkin filling — is actually made from a butternut-relative variety (a moschata) called Dickinson, not the round orange pumpkins on porches. The carving pumpkins are watery and stringy; the cooking varieties are denser, sweeter, and meatier.

Libby’s, the dominant U.S. canned pumpkin brand, grows and processes its own proprietary Dickinson-derived variety. Reading “100% pumpkin” on a can is technically true — it’s a pumpkin, just not the orange kind you’d expect.

Giants

Competitive pumpkin growing has produced specimens approaching 1,250 kg — single fruits weighing more than a small car. The current world record is 1,247 kg (set in Italy, 2023). Growing a giant is a year-long project: special varieties (Atlantic Giant), individual hand-pollination, careful soil management, hourly attention through summer, and a single fruit per plant absorbing all the resources.

The giant pumpkins are not eaten — they’re inedible due to size and water content. They’re grown for sport.

Seeds — a separate harvest

Pumpkin seeds (pepitas) are a substantial food in their own right. Mexican cuisine uses them ground into mole verde and as a thickener. Roasted and salted, they’re a popular snack, especially in Eastern Europe and the Middle East.

The seeds are unusually nutrient-dense — high in protein, magnesium, zinc, and unsaturated fats. A half-cup of pumpkin seeds provides roughly the daily requirement of magnesium.

Halloween’s American invention

The jack-o’-lantern — carving a face into a pumpkin and lighting it from within — is an Irish tradition that originally used turnips (which is what was available). When Irish immigrants reached North America in the 19th century, they discovered that pumpkins were larger and easier to carve, and the tradition transferred to the new vegetable. Today’s million-pumpkin Halloween market is essentially a 19th-century Irish-American invention.
