As soon as I put it in the ground, it threw up a new leaf right away and has continued making more without stopping. It is putting out several runners. Leaves emerge green with purple veins and then quickly turn dark purplish black all over. My plant is facing south west, getting hot, late afternoon sun. I keep it very moist and it is doing well.
