$75 Gift Certificate - Greensgrow Farm. Greensgrow is the nationally recognized leader in urban farming and is open to the public from early spring through Christmas. A small but dedicated staff runs a multifaceted operation, including a nursery, a farm market, and a Community Supported Agriculture (CSA) program, proving that abandoned land is only abandoned if we choose to leave it that way.   The Farm Stand and Nursery is open seasonally at their 2501 Cumberland Street location in Philadelphia. It is accessible by public transportation and plenty of ticket-free parking is available. Credit cards are gladly accepted.
