This plant looks like it was designed by a committee that started with a potato, decided that it should grow leaves like lambs ears (on stalks) and then have tubular flowers like a cestrum! Native to Brazil where it grows at high altitudes, Sinningia leucotricha, is commonly called Brazilian Edelweiss. It thrives on neglect. This one sits in our kitchen window where it gets filtered sun all day and it gets watered occasionally. It might need repotting one of these years but we've had it 3 years and it's still in the original pot.
