Ranunculus lappaceus, commonly known as the common buttercup, Australian buttercup or Yarrakalgamba, is found across eastern Australia. Like buttercups elsewhere, it is a perennial herb with yellow flowers appearing in spring and summer. James Edward Smith described it in 1815, and it still bears its original name. It is a member of the large cosmopolitan genus Ranunculus, known as buttercups. The species name is Latin "with burrs". Ranunculus lappaceus adapts readily to cultivation in acidic soils in sun or part-shade. It can be grown in rockeries or general bedding.
