G. rivale is pollinated primarily by bees, less often by flies and beetles. As the flower matures, elongation of the stamens ensures it self-fertilises if not already cross-pollinated. The flowers stigmas mature before the stamens. It begins flowering a little earlier than G. urbanum, so early pollinations will be within the gene-pool of the single species. The seeds of Water Avens are burr-like, and are distributed after being caught in the coats of rabbits and other small mammals, and by rhizomal growth
