Which of the plants covers a larger part of the world, Calibrachoa or Astilboides?
Calibrachoa Calibrachoa (ca-libra-KO-a) is a genus of plants in the Solanaceae (nightshade) family. They are evergreen short-lived perennials and subshrubs with a sprawling habit, with small petunia-type flowers. They are found across much the same region of South America as petunias, from southern Brazil across to Peru and Chile, inhabiting scrub and open grassland.
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.
