Items such as tyres, teapots, watering cans, wellies and coloured colanders all make great unique hanging planters, or you can easily use hanging baskets for a more classic look. Some plants that work well in hanging containers are Bacopa, Ivy and Lobelia.
If you are overlooked, you might consider a canopy of plants. A small wooden pergola draped in wisteria or clematis will lend some privacy and a little shelter for your garden furniture. Another option is an archway adorned with trailing plants.
