The type genus for its family, the Ranunculaceae, this is a widespread group encompassing some 400 species of annuals, biennials, and perennials, many of which are cultivated, while others are admired in the wild, and some are despised as invasive weeds. The foliage varies markedly, though glossy, leathery, kidney shaped leaves and deeply lobed leaves predominate. The flowers, too, are often glossy and they are borne singly or in small clusters through spring and summer. Most species have yellow flowers but cultivated forms occur in many colors, such as white, pink, and orange. Raunculus is Latin for little frog, a name given by the Roman Pliny because of the wet conditions in which these plants are often found.
CULTIVATION
Commonly known as buttercups, these plants are very hardy and will grow in a wide range of conditions but they prefer to have their roots kept cool and moist. Many species have trong rhizome that can be invasive if care is not taken to ensure that they are planted where they can be controlled. Propagate by division or from seed. Mildew can be a problem in autumn.
Top Tip
Adaptable to most conditions and soil types, buttercups will bring sunny colors to border or pond edges.
