If the photo in The Book is correct, then this is not "Excellent". And, this is "Excellent" from my garden, purchased at Home Depot and marked. The color is mostly green going to deep red, as it's planted in a very dark area.
Here's it's home for the winter. The Dieffenbachia bowmannii to its left is a piece saved from the original plant purchased 40 years ago at EJ Korvettes in West Orange, NJ. The troll was a gift from the King of Sweden. Well, no he really wasn't the King of Sweden, but it said so on his hat.
