I spotted this garden recently from a friends balcony and had to take a picture. I usually am only able to see these while looking up from street level, so I only get a hint of color and waving tree branches. Or I see them as the train flies by and there's no chance of a photo.
This one looks quite well-established with a variety of plants. Complete with a glass greenhouse and netting to swing over the top to provide a bit of shade and protect tasty berries on what I think just might be blueberry bushes from birds, it looks like a lovely little getaway. I needed a telescope to get a REALLY good look, which would have felt a bit like being a garden stalker. (There's a good pun in there that I need to work on, I think.) These photos will have to suffice for the moment.
