A community garden will have to determine if they allow perennial growing plants or if they only allow annuals. Perennials can be great additions, as people enjoy growing and eating asparagus, strawberries, raspberries, tree fruit and others.
Perennials remain in the ground year-after-year, and if not well-maintained they can become weed-infested and an eyesore. Gardeners would need to commit to renewed usage of a perennial plot. However, existing perennials could be seen as a bonus for someone taking over a plot in the future.
Some gardens want to encourage pollinators or beneficial insects, and they will request that everyone plants a row of flowers or other plants that attract these species. Many flowers, forbs, trees, shrubs and herbs will attract pollinators. University of Minnesota Extension provides this Plants for Pollinators List for attracting bees and other pollinators.
