Cucurbita — 27 species

Cucurbita is a genus of warm-season vining or bushy annuals from the Americas, encompassing familiar crops such as zucchini, pumpkin, butternut squash, and acorn squash. All species demand full sun — at least six to eight hours of direct light daily — and consistently moist, well-drained soil; they need roughly one inch of water per week, delivered at the root rather than overhead. The genus is confirmed non-toxic to cats and dogs by the ASPCA, making it one of the safer choices for pet-friendly edible gardens.
