Feathery foliage and a simple daisy on a tall stem — the airy insectary that does not shade a vegetable the way sunflower can.

Cosmos is a Mexican annual with thread-like leaves and flowers that look like they were drawn with a clean pen. It self-sows if you let a few heads ripen. Bees and hoverflies use it all day. Plant it behind lettuce in spring and beside tomato in summer; the foliage is light, not a tent. Cosmos sulphureus is the hotter orange cousin, just as easy. Neither is a salad plant.
