I have had this plant for 3 years. I have it in a pot without drainage because it almost died because it has to be so moist. I think it is a bog plant. After I put it in a bog situation I have had to divide and share with friends. Because it started to grow like a weed.
Because of my climate I have to grow it in a pot and bring it inside in the Fall.
I give it morning Sun about 4 hrs no more or the leaves started to burn.
