Originating from Mexico, Cosmos bring the spirit of a fiesta to your borders and containers. Supplied as a scintillating selection, from sizzling red and romantic pink to crisp white and pastel lemon, this collection produces armfuls of uplifting blooms to brighten your planting scheme. Flowering from July to October, the open blooms reveal a yellow centre packed with pollen and nectar, a feast for bees and butterflies. The bountiful blooms look wonderful when arranged in a vase for an airy, natural floral display. The more blooms you cut for the house, the more will magically appear. After all risk of frost has passed, this half-hardy annual will happily grow in any well-drained soil, in sun and part shade.
