I ordered about 30 different sedum plugs from Mountain Crest Gardens
last year for a very resonable price. They have a descriptive catalog,
but no photos unfortunately. www.mc-garden-gifts.com

Santarosagardens.com seems to have sedum ogon in stock, so does
worldplants.com and singingspringnursery.com. Do an image search on
google and then you can see what sites each image is from. That's how
I found these.
