Unfortunately, there isn't any room to plant anything else there. The area to the right is filled with the rodgersia you can see in the clematis picture, and euonymus:
The bed across the front porch is only about 12-14" wide as the driveway comes right up to the porch. It's surprising really that anything will grow there at all as the soil is very poor, it's under the roof overhang so is fairly shaded and dry, plus there is lots of reflected heat from the driveway, with salt in the winter!
The pots with the wigwams are peas. The backyard here is almost completely in shade so there's no room there for a vegetable garden. All the edible things are in pots on the driveway, in the herb bed (that's culinary sage that is blooming with the tall spikes) or tucked into the front flower beds. There are about 16 big pots on the driveway - 6 pots of peas (each pot has a variety with a different maturity so I get a succession of crops...); 5 pots of highbush blueberries with lettuce as a 'groundcover' around the base of the blueberries; 4 big pots of strawberries that are currently producing about a pint a day; and a pot of garlic. The blueberry and strawberry pots spend the winter in the unheated garage. There are cherry tomatoes in the herb bed and DH has put garlic in any place he can tuck it into in the flowerbeds.
