When the weather cools and dips into freezing temps I have tons of chickweed that springs up like crazy. It is delicious too. Early winter and later winter-early spring are best for them it seems. My chard is still doing well too. I'll be cleaning it up later on and putting a cover over it. I just put in a bunch of black-painted plastic soda bottles filled with water around the plants to help them cope with cold nights and frosty mornings.
