The garden tour thing is going on in my city. This year you can just wander around people's yards (those that have a garden tour sign) at will, which is fun. Some friends of my mother have the most amazing garden. They fill up their front yard with vegetables and flowers and the backyard is almost completely full plus paths and numerous seating areas.
We went by the other day and my favorite thing is that they've put up numerous large mirrors on the back fence. You don't notice the mirrors until you're right up close to them. Just glancing through the yarn they extend the garden so perfectly and make the tall back fence more appealing. They also keep the compost pile and other utilitarian things tucked inside the garden where they're accessible but half hidden among other plants.
It is really my idea of a perfect garden and makes me think of childhood. We always had a big garden with lots of vegetables, and while it wasn't so organized and prettily laid out, it was quite full. Plus we were always being dragged to various country greenhouses when I was a kid so most nice gardens remind me of those places as well.
