In this bed, you can see curly kale (blue-green), dill (feathery), mustard greens (light green, rounded leaves), and other salad greens (endive salady thing on the bottom left, black-seeded Simpson lettuce on the top right). I like to mix the plants like this, because they each take different nutrients from the soil; however, I'm aware that this is not the best thing to do from a crop-rotation perspective.
For those who think that global warming is a myth, you can see I'm harvesting bell peppers in Feb-March. Admittedly, the fruit are not growing much in the winter, but the plants are overwintering nicely outside. I have now re-potted these plants into larger pots, and I'm hoping that as the weather warms up, these plants will resume growth and make even larger plants this year.
