Sinningia eumorpha has flowers with a yellow stripe down the center of the tube. There are purple markings in the yellow stripe; The corolla itself is either white (as here) or lavender. The white seems more attractive to me.
Unfortunately, this particular plant is no longer alive.
Sinningia eumorpha has been used a lot in hybridization, and was one of the main parents of the xGloxinera hybrids of 50 years ago. It brings a lot of good qualities to hybrids, such as compactness, good leaf texture, and quickness to bloom from seed. This species usually has only one flower per axil, so increasing the flower count by appropriate choice of breeding partner is one of the goals when hybridizing with this species.
Bill Price crossed the variety S. eumorpha 'Saltão' with S. sp. "Ibitioca" to get a nice hybrid.

Horticultural aspects |
|
| From seed | 19 months to bloom, under my conditions. You can almost certainly do better, since S. eumorpha bequeaths rapid maturation to its hybrid progeny. |
| Hardiness | Has survived 28F (-2C) in my yard |
| Recommended? | Yes, with reservations. I have not had a lot of luck keeping plants of this species alive for more than a few years. On the other hand, they have nice foliage, and interesting flowers (especially if you like a lavender/yellow color combination). S. eumorpha is a superb parent for hybridizing, however. |
