Sonata Mix delivers the buoyant look of cosmos on neatly proportioned plants. Magenta, white, pink, and rose flowers hover over feathery foliage, forming a bright chorus without the height of classic cottage-garden strains.
At 2½–3 feet, the plants fit naturally into mixed borders and roomy containers. They branch freely, welcome pollinators, and produce armfuls of slender-stemmed flowers for easy summer bouquets.
