Hello all! This is one of the most productive collard greens out there. It's also very hardy and ready in about 60 days; grows pretty tall. This will put a lot of good greens on the table. For are farmers market friends, these will not wilt and will hold up on market day. For our market growers, if you order a one ounce pack, you will be fine. For the home gardener, one or two packs are plenty, and our packs are big. Our collard greens are Non-GMO and Heirloom. Happy growing!!!
