This Brazilian native is unique for a few reasons. It is tuberous species, but does not have a dormancy period, and can even flower year-round. Its leaves also are covered in a sticky residue that makes your own fingers self-sticky after touching it. I’m sure there is a more appropriately botanical word for it, but somewhere between waxy and sticky. The flowers are bright orange-red and the stems and abaxial leaf surfaces are covered in thicky, wooly hairs (that also give off the secretion). The tuber itself can be enormous, for even a small plant. The tuber for the plant below is nearly half the size of the foliage.
