Wild Cucumber (Marah macrocarpa), also known as manroot or bigroot, is a fast-growing vine that appears in late winter after increased rainfall. Known for its hairy shoots, stems, and leaves, it can scramble or climb up to 20 feet long. The vine produces small white flowers in early spring, followed by large, spiky fruit that forms after flowering and grows as the season progresses. The plant becomes completely dormant in summer.

With its rounded, five-lobed leaves and spiral tendrils at the growing tips, this plant is adaptable to various soils and is drought-tolerant. However, it is toxic, so care should be taken. Wild Cucumber hosts up to four species of butterflies and moths.
