I am growing peas, spinach, carrots and lettuce in pots on my patio. Small tomato cages offer support for the vining peas. I think this will make a charming planter -- some pea tendrils climbing up the metal spokes, others cascading over the pot's edge.
I positioned the tomato cage on the north side so it -- and the vines that will cover it -- won't cast too much shade on the emerging lettuce and carrot seedlings seen behind. In a few warming weeks, however, shade may be desirable for the lettuce, and I can simply rotate the pot. (Lettuce likes cooler weather and will quickly bolt and go to seed in intense heat.)
If you'd like to try such a planter, a great pea seed variety is Lincoln. In my zone, Zone 5, it can be planted as late as June, and will still produce in 90-degree weather.
I planted the pea seeds in a circle, with the idea of slipping a tomato plant into the cage later in the season. Here's a picture of last year's "side salad" of cherry tomatoes and lettuce.
