Which of the plants covers a larger part of the world, Calibrachoa or Astilboides?
Astilboides Astilboides, a genus of the saxifrage family containing only one species, a herbaceous perennial once included in the genus Rodgersia. It comes from China and differs from its former relatives mainly in its leaf shape. It is grown for its huge bright green, circular leaves to 36 in (90 cm) across with the stem attached to the center, and large fluffy racemes of tiny white flowers produced in summer.
Ranunculus calandrinioides Ranunculus calandrinioides (high alpine buttercup) is a species of flowering plant in the family Ranunculaceae, native to the Atlas Mountains of North Africa. Growing to 20 cm tall by 15 cm broad, it is an herbaceous perennial with broad, grey-green leaves which die down in summer, and white flowers, often tinged with pink, in winter and spring. It is one of the earliest buttercups to flower.
