Cosmos ‘Rosetta’ produces semi-double, soft pink and blush blooms which are subtly striped with a delicate yellow centre. The flowers are carried on slender, branching stems above finely divided foliage, making them attractive in the garden and perfect for cutting. This variety adds a graceful touch and long-lasting colour to borders, cottage gardens, and floral arrangements.
