I'd like to know the name of this plant. It grows in a very shady outdoor atrium at my office (these get almost no sun), and I really like the look of the plant, and the flowers. I want to plant it in my yard. It's not terribly clear, but the leaves are very long (to about 2 feet long), and each about 2-3" wide. They are very dark green and shiny. This image shows mainly what the flowers look like. There are several of them planted in the atrium, mostly about 3 foot diameter overall. All the flowers grow in these clusters. Thanks!
