Pumpkins are warm-season cucurbits central to Australian food culture. Three species are commonly grown: C. maxima (Queensland Blue, Jarrahdale), C. moschata (Butternut), and C. pepo (Golden Nugget). They require long warm seasons, ample space, and insect pollination. Excellent storage crops lasting months after harvest.
