While visiting the greenmarket at Grand Army Plaza, looking for an office plant, the sign at the New Leaf farm stand said grown in South Bronx. New Leaf, a drug-free work experience program for homeless men and women trains and employees through a nontraditional program. Workers grow plans and herbs in two greenhouses an open garden and courtyard. They also work in an herbal vinegar enterprise, creating, under strict conditions, flavored vinegars from the herbs they grow. These products are sold in Greenmarkets in Manhattan and Brooklyn. All profits are plowed back into the program.
