I know it's also the name of a very sweet garden centre not too far away but I love The Secret Garden (and it seems quite secret - can't quite imagine where it is and I walk along to Shannons a fair bit). Otherwise maybe: Forest Garden, The Hidden Garden? Like the idea of seeing some fairies there as well as some stag beetles (did no one else like that idea?). Btw Greensleeves - you have a looney neighbour - don't recommend the window cleaners to them!
