About
Cosmos bipinnatus 'Cupcakes Mixed' are upright, bushy annuals that can reach heights of up to 90 cm. They feature finely dissected green foliage and produce blooms from midsummer until the first frost. The unique flowers, measuring 10-12 cm in diameter, display outer rays that are fused at the base, creating a bowl-like shape around a yellow center. These blooms can be single or semi-double, with colors ranging from white to pale pink, and pink with deeper pink tones near the base.
