Plants on the top of a wall. A photo by one of my contacts Greg Douglas. Mostly I think of plants as rooted in the soil and forget they don't stay still. But the London's Pride I planted years ago moved through the fence to Jen and looks much better there than it did with me. Euphorbia crossed the garden path to a new location. Day lilies sneaked in from Debbie's. And a mysterious iris which appeared from nowhere in Jen's garden has now turned up in mine. All on the move. Keeping their eyes open for a better place to live. Somewhere to flourish and grow. Somewhere the next generation will do well. Will build a community.

And it mostly works. The established residents move over a bit. Bare patches of ground get occupied. Sometimes there are unusual combinations I would never have thought of. Beautiful surprises.

There are the odd thugs on both sides of course. Plants that look great but try to take over. Plants that don't look so great. Sticky Willie that was invited in by my old cat. Jen and I pull it up and laugh because it reminds us of the Ginger Peril. It's part of our past. No getting rid of it now and we don't care. The garden is better off for a bit of informality, flexibility, freedom. The surprises of plants on the move.
