Pumpkins are round with thick shells that are usually orange but can also be green, red, white or yellow. Pumpkins contain pulp and seeds inside. People carve pumpkins into jack-o-lanterns for Halloween decorations. Pumpkins typically weigh about 13 pounds, but pumpkins grown for competitions can weigh more than 1,000 pounds.
Pumpkins have thick stems that are left attached to prevent rot, when harvesters trim off the vine. Ripening pumpkins change colors during the ripening process from green to yellow to orange.
One organic farmer developed a process that grows Pumpkinsteins. He grows pumpkins that look like the Frankenstein monster by putting newly-formed pumpkins into molds and letting them grow into specific shapes, as of 2015. The farmer plans to grow white pumpkins inside skull molds and add heart-shaped pumpkins for Valentine's Day.
