I just returned from a week in the romantic city of Venice, Italy. Unless you hire a water taxi, Venice is a walking city, uniquely situated on a group of 114 islands, some only large enough to hold a single home. There are over 400 foot-bridges connecting the islands. 

Italians are very innovative when it comes to gardening. There is very little  unpaved ground, consequently most plants, annuals, vines, perennials and even trees grow in pots. Here are some pictures of the  houses covered in vines, window boxes, containers and peek-a-boo gardens I saw.

The flowers match the docking poles.
