I love bird cages, there is something calming about them, although in reality they say the contrary, as they capture birds. Paint the wooden bird cages in bright colours and add as a feature to a dull corner of a room or hang from the branch of a tree. you can plant a plain old wire one with seeds or a plant and watch it bloom.
i love unusual vessels for plants in gardens – i have trugs and crates to house my pots on my balcony – you can pick lots of these things up at kemptom market. i love the trolley at petersham nurseries stacked with plants.
