Green Guerillas, an organization founded by Liz Christy that popularized guerilla gardening and established the Bowery-Houston Community Farm Garden in 1973 (now the Liz Christy Community Garden). Today, Green Guerillas supports community gardens across the five boroughs. They use a mix of education, organizing and advocacy to help people cultivate community gardens, sustain grassroots groups, grow food, engage youth, and address issues critical to the future of food justice and urban agriculture.
