Gardeners aren’t generally known for their civil disobedience, yet in the last couple of years several have run afoul of local officials for tending vegetables in their front yards. In Ferguson, Mo., a stay-at-home father was ordered to dig up his 55 varieties of edible plants. In Tulsa, Okla., a gardener who didn’t want to remove her veggies and medicinal herbs saw them largely cleared by the city.
