Here's the final product.
I used a red-quarts flag that I cut down on the edging. The red color is more a brown color, and the neat thing was the the block had a metallic sheen to it similar to lead, or pencil lead on a sidewalk.
O.K., I think it turned out well, better than I expected. I talked the m-law into buying some ferns to go along with the grasses she had bought previously.
