Spinyfruit buttercup can be found growing natively in open fields, ditches and lawns as well as along roadsides. In addition, it can be found growing in sandy marshes, around ponds and streams and often in shallow water. Spinyfruit buttercup generally cannot be successfully grown in areas where the soil quality is of a poor quality which lack lack sufficient nutrients. The leaves are a beautiful shape and dark green color, but the blooms are small (up to 15 mm in diameter). The pistils develop into achenes with short spines; however, they have a spine-free edge. The prickly achemes distinguish this species from all other buttercups other than corn buttercup which has deeply divided leaves and a spiny-edged seed. The flowers are hermaphrodite (have both male and female organs) and are pollinated by flies. Considered a medicinal herb, it is used in the treatment of intermittent fevers, gout and asthma.
