Polysianka is a perennial herbaceous dioecious plant with quadrangular stems that can reach up to 7 meters in length. The leaves are opposite, entire, lower ones three- or five-lobed, or divided with a heart-shaped base and coarsely toothed lobes. The upper surface of the leaves is smooth, while the lower surface is rough. Male flowers are arranged in loose axillary panicles with whitish or greenish tints, while female flowers are in terminal and axillary heads called 'cones,' formed by the growth of large scale-like bracts creating a soft green structure.
