Cosmos seeds bring tall, airy growth and generous summer flowering that lifts borders, beds and cut-flower patches. Known for their daisy-like blooms and light, feathery foliage, cosmos adds movement and soft colour without taking over the space. These varieties create a relaxed, informal look that works well with cottage-garden styles and mixed plantings, providing steady colour right through the season.
