What makes a garden a cottage garden (you know, besides the obvious "hence the name" answer)? There really are no rules when it comes to designing a cottage gardens. They often include herbs, you can work in vegetables, roses, boxwood, gravel paths, arbors, funky gates, picket fences, hollyhocks, benches, bistro sets, sculptures, birdhouses...you name it. Charming little outbuildings like potting sheds and playhouses always have a home in a cottage garden.
