Cosmos Seeds

Add colour and charm to your summer garden with cosmos seeds from Johnsons. These vibrant, daisy-like flowers, with their dainty petals, bring a romantic and whimsical feel to any outdoor space. Choose from a gorgeous range of colours, from soft pinks and pure whites to rich purples.

Cosmos flower seeds are perfect for adding height and movement to beds and borders or filling cottage gardens with masses of bright blooms. With their long, slender stems, they also make excellent cut flowers for summer vases and bouquets. Pair them with airy grasses or taller blooms like sunflower seeds for a balanced, textured look.
