Gardening vertically's in vogue at the moment. We have Patrick Blanc's amazing creations which look like the Hanging Gardens of Babylon; the RHS shows have been full of edible verticals this year, like Freshly Prepped at Chelsea. There's lots of absolutely stunning ideas and results. I've also seen a couple of vertical gardening products at the shows, so you can go and get the look yourself.
I even considered them for my boring fence project. Using climbers, vines, trellis and wires is just so yesterday, especially when you can install something exciting to do the same job, with very different plants. However, I still haven't got a clue how you'd look after those fancy planters effectively and without bringing the fence down. Sometimes it's good to get out and about and have a look at what the neighbours are doing. The pictured Euonymus from just round the corner, is a good reminder that sometimes simplicity is best.
