Tolumnias can be tricky to grow. They are intolerant of overwatering and will drop rotten leaves when grown too wet and too shady. And - any scale within 10 yards with find their way to these plants and and love to snuggle in those freshly grown fans.
This little plant is a tough survivor, I thought it was really done after I had to treat it again for scale. But it rebounded with a new growth and a little spike.
I bought it as Tolumnia Ducky Doo, but only Tolumnia Ducky is registered with the RHS.
