Overview
Pumpkin and zucchini, known scientifically as Cucurbita pepo, are native to the central regions of Mexico. These plants thrive in full to partial sun and require moist soil that can be light (sandy), medium, or heavy (clay). They have a hardiness range from 2 to 11, making them suitable for various climates within their native range. Both edible and ornamental, these plants are valued for their fruits, flowers, leaves, and seeds. One distinctive feature is their ability to grow up to 0.6 meters in height with a spread of about 1 meter, while another notable characteristic is their light requirement, which can vary from full sun to partial shade depending on the specific cultivar.

Pumpkin and zucchini (Cucurbita pepo) thrive in full to partial sun, requiring moist soil that can be light (sandy), medium, or heavy (clay). These plants are annuals, growing up to 0.6 meters tall and spreading about 1 meter wide. They are hardy in zones 2-11, making them adaptable to various climates within temperate regions. For propagation, seeds can be sown directly into the garden once the threat of frost has passed. Regular watering is essential for healthy growth, but ensure the soil drains well to avoid waterlogging.
