Sinningia douglasii plant

S. douglasii was distributed for many years as S. verticillata. It is a variable plant in both flower and foliage. While this specimen (and this one) have distinctly pinkish flowers, some clones are more yellowish in tone, albeit with the maroon markings. This is well illustrated in the 19th century botanical print of "Gesneria douglasii", which also shows the characteristic habit of the plant, with successive whorls of leaves and flowers.
This species naturally grows with its tuber partially exposed above the ground, as illustrated by this photo. A close-up of a flower shows the patterns in the face and throat.
