A carved pumpkin lantern with a cheerful smile

A large, classic jack-o'-lantern rests upright in a standing position. The carved squash displays pointed triangular eye cutouts, a matching small triangular nose, and a wide grinning mouth. At the very top, a sturdy stem points upward from the center of the pumpkin crown.

The origins and science of autumn pumpkins

Pumpkins are technically botanical berries known as pepos that belong to the gourd family alongside cucumbers and squashes. The tradition of carving faces into root vegetables began centuries ago in Ireland, where people carved turnip lanterns before switching to native American pumpkins. Healthy pumpkin skins get their bright orange coloration from carotenoid pigments, which are natural organic compounds produced during ripening.

Authentic colors of carved pumpkins

  • Pumpkin outer skin: deep orange, pale yellow-orange, or muted rust
  • Top stem: woody brown or dried olive green
  • Carved inner cavity: warm glowing yellow or pale cream
  • Inner pulp lining: soft yellowish-orange fiber
Questions and answers

Questions and answers

Why do pumpkins turn from green to orange as they mature?
As pumpkins ripen on the vine, chlorophyll breaks down and exposes underlying carotenoid pigments. Sunlight accelerates this natural transformation, changing the exterior rind from dark green to rich orange tones.
How long can a carved jack-o'-lantern stay fresh outdoors?
Once a pumpkin is cut open and exposed to air, moisture loss and natural bacterial growth cause it to soften within three to seven days. Keeping carved lanterns in cool, shaded areas helps prolong their structure.
What makes pumpkin stems turn tough and woody before harvest?
As the growing season ends, the vine naturally dries out and restricts fluid flow to the fruit. This hardens the stem into a protective wooden handle that seals moisture inside the pumpkin rind.
