Here in the South, Korean red mustard and ornamental kales are common for winter plantings that are both pretty and edible. This time of year though, they go to seed, so the summer vegetables need to go in. Peppers are attractive plants, and bear all through the season. Colored chards are another possibility, more of a winter vegetable for the South and a summer vegetable further north. Tomatoes get less "pretty" as they sprawl all over the place, but with constant maintenance, you can keep them within bounds and looking good. That advice goes for other vining plants as well: cucumbers, squash, small melons, nasturtiums.
I get the idea that people expect landscaped public spaces to produce a lot of flowers and "look pretty", and they don't have the permaculturalist's eye for how things grow and change through the seasons. I have to be vigilant to collect seed from landscape plants, before the property owner complains to the landscapers about the looks, and then they go out and deadhead all the plants. I try not to deadhead in my garden spaces, not unless it is a weed that I am trying to suppress, like nightshade.
Bottom line, my garden wouldn't make for a pretty raised bed at the local library. Similarly, I wouldn't want to forage for dinner among the raised beds that look pretty in the public spaces around town.
