Why are Giant Pumpkins different shapes and colors?
Pumpkins grow in many different shapes for a variety of reasons. It’s all in the genetics of the seeds. Most seeds are cross pollinated to produce offspring with increased weight, and not pretty colors and shapes. After all most growers are competing in giant pumpkin weigh offs, not beauty contests. Some growers do grow for color and shape. Weather is one factor, since pumpkins were originally grown in northern climates those are the ones we recognize as “traditional”. As pumpkins moved with the settlers to different climates throughout the United States, different species had to be developed depending on the climate.
