When we moved into our condo the previous owner was kind enough to leave the flower box that hung over the balcony railing. It did the trick but was just a plain green box and not nearly as pretty as the wall troughs (which I just learned they’re called, by the way) that I would see all over. I’ve been looking for one of those for two years but couldn’t find one that had a hanging support system that looked like it would work. It turns out, I just wasn’t being creative enough. Not too long ago we were at this great store in Chicago called Sprout when the really helpful salesperson told me all I needed to do was attach it to the railing with zip ties. Genius! We finally have our new box up and planted and now I just can’t wait for all of the Impatiens to bloom.
