Make it Pretty. For cozying up and bringing lushness to an outdoor space with too much hardscape and bare walls- well yeah, containers can do that. As the design rules go, groups of odd numbers are best (unless they are flanking an entry way or focal point, in which case 2 works)- 3 being the golden number for a cluster of pots, especially in a corner- I like to go with similar or same exact style/color pots in three varying sizes- though varying colors in the same material and color story can have a fun impact as well. For choosing plants in a pot I usually stick with three (or 5) and like to refer to a term I WISH I coined, but heard from a nurserywoman, who surely heard it somewhere else (ah yes, the derivation has yet to be tracked down)... anyway, rambling aside, it goes like this: The Thriller, The Spiller and The Chiller (See sketchy and 100% original ADh+d drawing, right). Your thriller- she is the star of the pot- the tree, the specimen, the tallest and brightest. Then your spiller- she's a cascader- for example, your ivy, bacopa, campanula, creeping jenny, or sedum. Finally you got your chiller. He's, well... chillin... anchoring the pot-scape together between the pendulum swings. Together, when done right, the three sing. Succulents are especially great for this as they do well with part sun and won't hate you if you neglect watering- a good succulent triad as illustrated on the far left is aeonium, echeveria and a cascading succulent, such as a sedum. Go-to "thrillers" include Japanese Maples, Citruses, Abutilons, and Cordylines/Phormiums to name a few. And remember When choosing plants be sure to select contrasting and compatible colors and textures (not all the same shade of green).
Make it Edible. Edibles will grow in your container like a boss. Some invasive ones like mint, you may
even prefer to keep strictly in the pot. Some tried and trues: Herbs, Lettuces and Chards (great for part shade), Annual Veggies (I grow tomatoes in containers every year with excellent tasty results), Berries, Dwarf Fruit Trees and Citrus, and Perennial Veggies (many peppers, including serranos are a great "perennial veggie" for containers in the bay area).


Cheers, and happy gardening!!
