My first thought when I saw this forum was, 'What is Cottage Gardening?' I love that the first thread I saw answers the question. This needs to be stickied.
When I was living in the Chicago area I noticed that the houses seemed to explode with life as soon as spring hit. Every single one had some sort of garden. One close to my apartment was quite different than the rest. Most did a formal garden in their little postage-stamp front yard with very well-defined lines and very manicured bushes. But, this house was a riot of what looked like plant chaos. I loved it. Now I have a name for the style.
Thanks!
