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.
Psychotria capensis The Bird-berry ("Psychotria capensis" ) is a southern African evergreen shrub or small tree. It belongs to a genus which is used medicinally in many regions, 'Psychotria' being from the Greek for 'rejuvenating', in reference to the healing properties of certain species. Kew lists some 2,000 species of "Psychotria" growing throughout the warmer regions of both hemispheres, but only two of them occur in southern Africa, namely "P. capensis" and "P. zombamontana".
