I have several plants of this species, but none has ever even had flowerbuds. The stems remain on the plant all winter.
The tubers are interesting. See a picture of one oddball.
Sinningia bulbosa is one of the "Galea Group", a cluster of closely related species which all have flowers with an overhanging upper lip, formed by the two uppermost corolla lobes.
Mauro Peixoto's web site has a picture of the flowers.
One of the highlights of Ron Myhr's web site is his collection of antique prints, such as one of Sinningia bulbosa.
Sinningia bulbosa was first published (as Gesneria bulbosa) in 1818 by John Bellenden Ker-Gawler (1764-1842). It was a Rechsteineria and a Corytholoma after that. Hans Wiehler transferred it to Sinningia in 1978.
Etymology: from Latin bulba ("onion", or presumably other bulb).
