Pumpkin
Cucurbita mixta
Overview
A sprawling vine that produces the iconic orange gourds of autumn, pumpkins are deeply woven into harvest celebrations and food traditions across the Americas. Beyond the jack-o'-lantern, pumpkins offer nutritious flesh for pies, soups, and breads, and their seeds are a protein-rich snack packed with zinc and magnesium. Giant pumpkin growing is a competitive sport, with current records exceeding 2,700 pounds.

Growing Conditions
How to Grow Pumpkin
Pumpkin (Cucurbita mixta) is a vine that grows to about 5 feet tall and 8 feet wide.
Pumpkin is hardy across USDA hardiness zones 5–12. Plant it in rich, well-drained, loamy soil with plenty of compost, at a slightly acidic pH of 6–7.
Exact sowing, transplanting, and harvest months shift by climate zone — the planting calendar below lays them out for cool through hot regions. Its flowers appear from May through August, offering moderate value to pollinators. The details above are a starting point — your ground will teach you the rest.
Companion Planting & Soil
Pumpkin grows well alongside corn, bean, sunflower, marigold, and nasturtium — but keep it clear of potato.
