RANUNCULUS. Buttercup. Widely distributed, cold and temperate regions. A large, widely scattered group, known by way of some of our prettiest spring wildflowers as well as the garden ranunculus, R. asiaticus, one of the commonest of spring “bulbs”. Most have clustered basal leaves, round to oval in outline and often lobed or dissected, and stems of mostly 5-to 10-petalled blossoms with many stamens, the predominant color being one of several shades of yellow. Most are easily grown in sun or light shade and most soils, though other details of their culture and hardiness vary.
cortusifolius. One of the stoutest of the buttercups, this one has roundish, scallop-edged basal leaves 6" or more broad and sturdy 2’ stems bearing large, bright yellow blossoms in broad sprays. It is a winter/spring grower and may be dried out completely during its summer dormancy. Hardy to 20oF. or less.
