Join  Peterson Garden Project  during the entire month of May for our annual Edible Plant Sale geared toward  urban and small-space  gardeners and offering items you won’t see anywhere else in Chicago.  Buy organic plants, seeds, books, tools, compost, fertilizer, and more —everything you’ll need to get your edible garden growing. When you make a purchase, tell your cashier that you’re with Peterson Garden Project and a portion of your purchase will support our mission to recruit, educate and inspire everyone to grow their own food. Sale runs every day through May 31, 10 a.m. to 7 p.m. daily.
