We love the unrehearsed window boxes of fall, when enthusiasm for 'arrangements' gives way to improvisation. Wild weeds or roadside grasses are the unexpected ‘fill’ that bring a tired grouping back to life for a few more weeks. Chubby pumpkins, glossy eggplants, multicolored squash, Indian corn, garlic, and beets take the place of expired plants. Round shapes counterbalance stalky plants trying to outrun the first killing frost with a final burst of energy.
When planning a spring window box, think ‘texture’. Herbs are ideal because they flower in surprising ways and have such varied leaves. Blend soft, spiky, and feathery elements to keep the eye amused.
