Just a note that my regular peas were harvested yesterday. I got about two cups of pea pods (enough for one meal) and actually I was able to eat them without shelling, more like a snap pea. They were a lighter green but sweet and delicious!
The snap peas are starting to fill out now and they are a nice mid value green. Interesting in that they are slower to mature than the regular peas.
So far I would say that the vegetable that produces the most food per square inch or the most bang for your balcony planting buck is lettuce, believe it or not. The peas were really nice though.
