The shoots are hairy and contain clinging whiskers. Leaves are large, heart-shaped, with hairy edges. The root system of the pumpkin is well developed but shallow. Thanks to adventitious roots, it attaches well to the ground. Pumpkin flowers are intensely yellow and odorless. The fruit is a large berry, reaching a weight of up to 200 kg (the giant pumpkin can weight up to 800 kg).
