I have a small seedling of this plant, but others have grown it to blooming stage.
The picture above was taken by Dave Zaitlin, of his own plant.
This informative picture, taken by Karyn Cichocki, of her own plant, shows the flowerstalks and petioles growing directly from the tuber.
One might expect that this species would be closely related to another sinningia species which blooms directly from the tuber, namely Sinningia defoliata. Such is not the case, however, as they are in different clades. S. tuberosa is in the Sinningia clade, grouped around S. speciosa, while S. defoliata is in the Corytholoma clade, a group of mostly tall and/or sticky-leaved species.
| Plant Description |
|
| Growth | No stem |
| Habit | Rosette-like |
| Leaves | Petiole from tuber (judging by Sinningia defoliata and Sinningia helioana ("Santa Teresa"), which also have leaves which appear to grow directly from the tuber but which actually have petiole-like stems, the leaves of S. tuberosa probably are borne on very short petiole-like stems). |
