In cities and towns across North America, community gardening is flourishing. The American Community Gardening Association estimates that in the U.S. alone there are 18,000 to 20,000 active gardens. The gardens are large and small; formal and informal; urban, suburban, and rural. They operate on municipal land, land trusts, and private land; many are official, others are guerrilla acts of cultivation. Some community gardens are organized by hundreds of gardeners, others by just a handful. Some gardens allot plots to individuals; in others, gardeners work collectively. Community gardeners grow food or flowers, or curate art or natural features. The common element is that all of these gardens are created and maintained by members of the community for the benefit of the community.
