These herbacious plants do extremely well in moderate bright light. In extremely bright light the leaves get a bit more crinkled that would be desired. With 1/2 day sun, they do great.
Click on the images to see them full size. I still have the red one which changes color from scarlet to blood red depending on the amount of sunlight. My favorite, though is the one seen in the two photos on the left.
