Could be Lynn - you were probably on the Sedum page, and I have a picture of the plugs in production. I make lots of plugs for green roofs, which as you've probably become aware, over the past few years there has been phenomenal excitement over them.
My favorite way to supply plants for green roofs is by unrooted cuttings - I go out in the morning, snip away until I have several hundred cuttings, stick them in a flat overnight to dry, then pack them in a bag for shipping. Hardly any work for a good return. Plus my stock plants get pruned and I don't have to find a use for the cuttings (more plugs = more work!)
This is the same picture as on that page - is it the one you were thinking of?
