I took these pictures at a local nursery. They are not the best but the plants were massed together so it was hard to get a good shot. I'll add to data base.

Nice, although I would not necessarily put something in the database that does not accurately represent the plant. Maybe wait till you get a better picture? The 'Black Coral' is REALLY black....

Paul,
Thanks, that is my favorite plant. I have all shown but the 'Black Coral'. I have put mine in the data base so adding more pictures gives the viewer more different looks. My 'Silver Laurentii' losses it's silver color slowly during the summer with more bright sun. I have read that it's shade that causes them to green up but not in my experience.
