Cosmos are sun-loving plants that belong to the sunflower family. Originally native to Mexico and parts of the United States, these charming flowers have become a firm favourite in UK gardens, where they’re grown as half-hardy annuals.

Versatile and unfussy, cosmos do well in most kinds of soil and can be grown as bedding plants or patio flower plants. One of our favourite varieties is the Chocamocha cosmos, whose deep red-bronze blooms are known for their sweet chocolate-vanilla fragrance.

If you don't have the space or time to grow cosmos seeds, our premium cosmos plants offer a convenient solution. Simply plant your garden-ready plugs in a sunny, sheltered location with well-drained soil. Keep them watered during dry spells to enjoy a non-stop display of fabulous cosmos flowers from June to October.
