Boasting sumptuous, velvety cherry-hued blooms atop lance-shaped, blue-green foliage, ‘Cherry Chocolate’ is a standout in any sunny border, offering a striking contrast when paired with other vibrant hues. Awarded second place as Plant of the Year by the RHS at the Chelsea Flower Show 2024, this variety features the largest flowers among atrosanguineus cultivars, measuring 7cm (3in) across. Its allure is further enhanced by its chocolate fragrance emanating from its blooms, enticing both humans and pollinators alike. To safeguard against frost damage, consider protecting its tuberous roots with a cloche or overwintering in a frost-free environment, ensuring its beauty for seasons to come.



• Garden care:
  Plant Cosmos atrosanguineus in frost-free conditions, in a sunny spot with well-drained soil, spacing the plants 30-40cm (12-15in) apart. Water thoroughly, keeping the soil moist but not waterlogged, and mulch to retain moisture and suppress weeds. Fertilise in spring and mid-summer, and deadhead spent blooms to encourage continuous flowering. In cooler locations, dig up the tubers in autumn, reduce the stems to within 5cm (2in) of the roots, and store them in a cool, dry place for replanting in spring. Alternatively, mulch with a thick layer of compost over the winter to protect the plants.
