S. conspicua is in general appearance much like a pale yellow version of S. eumorpha, a species much used in hybridizing of miniature and mid-size sinningias. It is not clear that these species are closely related however, and there are differing opinions about this. Cultural requirements are generally similar. I grew this plant under flourescent lights, watered enough to keep the soil gently moist,and provided moderate amounts of balanced fertilizer.
In any event, this species is very attractive and under some conditions sweetly scented. It is not difficult to grow, and produces flowers that are quite large relative to the plant size. The leaves are soft and somewhat hairy, unlike those of S. eumorpha which are smoother, and usually darker and somewhat shiny.
It will be interesting to observe the effect of the inevitable hybrids of S. conspicua. With luck, they will introduce yellow into the hybrids of this genus, and have the kind of revolutionary effect that S. eumorpha had when it was first introduced.
A close-up view of the flowers of this plant illustrate the interesting markings in the throat. The species seems to be quite variable, as some individual plants have many more dotted and spotted lines in the throat.
