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.
Roscoea cautleyoides Roscoea cautleyoides is a perennial herbaceous plant occurring in the Sichuan and Yunnan provinces of China. The scientific name is also spelt Roscoea cautleoides (see below). Most members of the ginger family (Zingiberaceae), to which it belongs, are tropical, but "R. cautleyoides", like other species of "Roscoea", grows in much colder mountainous regions. It is sometimes grown as an ornamental plant in gardens.
