About

Cucurbita pepo serves as the foundational species for a variety of cultivars, including courgettes, summer and winter squashes, pumpkins, and gourds. These annual plants can exhibit either a trailing or bush-like growth habit. They produce yellow flowers, with both male and female blossoms appearing on the same specimen; the female flowers feature a small undeveloped fruit at their base. The fruits can exhibit a range of colors, including green as seen in courgettes, as well as cream, yellow, or orange, typical of pumpkins.
