Looking more like a miniature spiny watermelon than a cucumber, the fruit of Wild Cucumber (Echinocystis lobata) grows on an annual vine that can reach a length of 15 to 25 feet. The genus name Echinocystis comes from the Greek echinos for “hedgehog” and cystis for “bladder”, appropriately describing the prickly fruit. The puffy, spherical-to-oblong, green fruits with long, soft spines grow up to two inches long. Despite its common name, Wild Cucumber fruits are not edible, and can cause burning reactions in some people. When ripe, the fruit turns brown and dries up, bursting open at the bottom, ejecting four large, flat, black seeds.
