Dont try and do too much in a small space. Picking 3 or 4 different types of plants is usually best. Depending on location and sun exposure. Also adding texture with boulders or gravel can be a nice touch.

Start with asking yourself how you use the space. If seating or dining table is important, start there. Then plan for privacy and a sense of enclosure using shrubs. Chicago Roof Deck and Garden is correct. Limit the number of plants. We prefer lush/dense plantings and plants that look great all season.

If you're interested in having herbs around, I've found Seedsheets to make growing fresh herbs so easy in small spaces! Container gardening is great when you don't have a ton of space, and now I don't have to run out to the store whenever I need a sprig of fresh basil or parsley. What climate zone are you in? Since I experience frost in the winter, I just bring my bucket inside. Seedsheets.com
