This one occupied several hours. I took an old basket my girlfriend dug out of the garage and made a sempervivum landscape. This has at least 20 different varieties of semps and jovibarba, and was a blast to make. You can't tell from this photo, but I played a lot with height, and made little hills and valleys. I also used chunks of wood and stone in the landscape. The final product is about 24-30" x about 14-18". Click on the pic below for a larger version.
I made an indoor planting of five different kinds of haworthia here, using a pot I found in San Diego for $3. (It didn't have holes in the bottom, but the problem was easily remedied by a diamond-tipped drill bit.) From left to right, these are: h. parksiana; h. cymbiformis (variegated); h. truncata; [aack--not sure]; h. cooperi.
Next up: crassula coccinea (I think), surrounded by a cottony expanse of sempervivum arachnoideum, potted into a shallow square pot from Succulent Gardens. Here's a birds'-eye view. The semps become a kind of top dressing themselves.
Finally, I made this one using a gorgeous echeveria chroma ($1.98, Half Moon Bay Nursery) and some gasteria pups and small, misc. cuttings. I integrated random little metal objects my handy girlfriend was throwing away when she cleaned out her workshop. What would you call this--steampunk succulents?
