Buttercups are seldom considered any more than attractive spring wildflowers. But, several varieties can be very undesirable in turf. Bulbous buttercup, like all other difficult turf weeds, has the capacity to hug the ground and avoid damage. The bulb-like base of this perennial gives this plant the ability to resist long periods of dry weather. Leaves are on long hairy stems and divided into three main sections. Each section is then variously lobed and cleft. Flowers are bright, shiny yellow, with five to seven petals. They are almost round in appearance. Although bulbous buttercup grows most commonly form Newfoundland and Ontario south through Louisiana, it is also a problem in the Northwest.
