Cucurbita pepo
Pumpkins are vigorous annual vines grown for their large, colourful autumn fruits. They thrive in warm, sunny conditions and produce long, sprawling stems that can easily run several metres. Pumpkins are frost-tender and need a good, rich soil and consistent watering through summer. With enough warmth and space, they reward you with hard-skinned fruits that store well and are ideal for both cooking and seasonal decoration.
