Peter Smith is already wellknown for his ultra hip urban garden shop - City Planter - in Northern Liberties. Now, he's become the kokedama guru. Koke-what?

It's an interesting and highly decorative way to hang houseplants. But there are no pots. Plants are inserted into a mud ball - now we're talking fun - the ball is covered with sheet moss (live or dried), tied every which way with twine or string and hung from the ceiling.

This planting technique originated in Japan, but in the last few years a Dutch floral designer has come to own the concept. Fedor Van der Valk calls his creations "string gardens" and he uses crazy things like azaleas and fruit trees. Very dramatic, but not especially practical for over the sink.

Peter's designs are much more accessible. He uses succulents, ferns and other plants that are pretty and readily available. Perhaps you saw his kokedamas at the flower show this year or last. Peter says they sold well. They're a happy project - a bit messy - and the plants can last about a year if you water properly. That involves soaking in a bucket or sink, so this is only for the truly committed.

But think of the possibilities ... hanging gardens on your patio this summer!
