Round planting bed, 9ft diameter

What can you do in an urban/ small lot?    Here is ONE of my planting beds.   This round bed is about 9 feet across.    

Planted in it are:

Pecan tree
Serviceberry tree
Raspberries
Garlic chives
Asparagus
Lamb's quarter
self-seeding Chervil
Dill

Congratulations on your success Heather. I too have found that round beds are outperforming my rectangular beds. Several observations based on experience appear to account for this out here in New Mexico:
1. Circles can accommodate simple round sprinkler (cheap!), placed at center (with a short extension hose to edge and quick release fitting). Watering at various pressures allows the whole circle to receive appropriate water unlike difficult-to-manage drip emitters
2. Circles mimic nature. Shade of a slow growing bush or tree extend outward, gather wind-blown organics that feed and protect young plants at edges
3. A circle garden, like an island, looks very natural and inviting in an exposed location like the center of a yard as in Heather's photo
4. Circle gardens don't require carpentry skills to create straight edges and tight corners. Avoiding lumber saves money and allows the gardener to welcome the decomposition processes that feed plants
5. Circle gardens accommodate naturally crooked materials for edges: stone, branches, wattles. These edges are typically free
6. Circle gardens can expand outward over time as soil improves and tree drip lines extend outward

What else do gardeners love about circles?
