Tomatoes: Cosmos and tomatoes get along like old friends. Cosmos attract bees and other friendly pollinators, which often pay a visit to tomatoes while they’re in the neighborhood. As a result, tomato fruit set is increased. For the same reason, cosmos is a beneficial neighbor to squash and many other blooming vegetables.
Beets: Beets actually do fine without cosmos, so what’s the reasoning behind this combination? It’s mainly aesthetic, as the dark red beet leaves are striking against the colorful blooms and lacy foliage of the cosmos plant.
