I'm a volunteer for a small urban community garden, and we've just been granted a long, narrow, 40-foot strip of unused asphalt along a chain-link fence that borders a busy street. Our goal is to transform it into a productive pollinator and edible hedge to buffer noise and pollution, but the site is brutal—full sun, reflected heat from the pavement, and contaminated runoff from the road. We have a communal budget of maybe $500 for everything, and we need tough, deep-rooting perennials or shrubs that can handle zone 7a, be planted by volunteers of mixed ability in the next month, and eventually reach at least 4 feet tall to provide a visual screen. I'm overwhelmed trying to find a plant list that balances these survival needs with providing a long season of blooms for bees and some kind of edible yield, like berries or herbs, for the neighborhood.

Try a layered, easy-to-plant hedge: a tall backbone of elderberry and serviceberry for 6–10 ft height, midrow blueberries for edible fruit, and low currants or gooseberries as screen. Use a clean-soil berm on the asphalt edge, light mulch, and a simple drip line. It's volunteer-friendly, tolerates heat and pollution, and blooms for bees while delivering berries.
