Announcing "The Greenest Thumb": the Apartment Therapy contest for all of the urban gardeners out there. If you're in Chicago and are plant proud, get out the camera and take some pictures over the long weekend. This contest is open to all local gardens from flowerbox up to 600 sq. feet. We want to see a few great pictures and hear your resources and tips (200 words or less). Your entry should be your own garden, please. While each contest is local, The Greenest Thumb is taking place in all of the AT cities - let's show off just how green and gorgeous Chicago really is. We can't wait to see your flowerboxes, parkway plantings, roof deck containers, herb gardens and backyards! Send entries with "CONTEST" in the subject line to us at chicago(at)apartmenttherapy(dot)com. The deadline is Monday, June 5 at 6pm.
