The one thing we fear is that some people may take the plants, since they're so easy to carry away. Fortunately, it doesn't seem like theft is a problem here, but we have seen angry notes in other people's front yards condemning potted plant theft.
Potted plants aren't just for inside the home. We love seeing people use them for outside spaces too, especially in non-suburban areas, where green leafy things are more of a rarity. This particular home in Hayes Valley is one of our favorite examples of expanding your potted garden out from your private space into public space. We like to think of it as city beautification.
