The CSA's that deliver to Alexandria, VA and produce at the Del Rey and Old Town Farmers Markets are mostly NOT organic. For some reason organic and local is hard to find in Alexandria, VA.
Even' Star's greens and Mesclun salad mixes, which they offer in the winter CSA are excellent and better than what you get in the organic section of your market. The variety in the winter CSA is wonderful and delicious. One gets several types of sweet potatoes, for example, and exposed to new types of turnips and radishes. Early in the winter CSA, which includes the fall, one also gets amazing peppers and tomatillos. It is a really good value for the money. Each box contains plenty of greens and variety of other vegetables to make several meals.
