In addition to this, the city has become more aggressive about issuing $600 fines for plants deemed overgrown "weeds" (often arbitrarily-- Weed law in Chicago sends native plant gardeners to court) and we want to make it clear to neighbors and ticket writers that there is intentional gardening taking place, rather than neglect. Ginkgo hasn't encountered this and we'd prefer not to. We still have work to do, but this donation got us off to a great start!
Not all pretty plants are strictly ornamental. The aesthetics of chive flowers add a secondary benefit to a tasty herb. We generally treat the walking onion as an ornamental, but the tops make a great substitute for shallots. And potato flowers are absolutely gorgeous!
