Cosmos bipinnatus 'Sunset Yellow'
Delicate pale-yellow and creamy-white daisy-like flowers with golden centres and elegant, feathery foliage

Cosmos bipinnatus 'Sunset Yellow' is an elegant annual flower admired for its delicate, softly coloured blooms in pale-yellow and creamy-white shades. The single, daisy-like flowers feature bright golden-yellow centres and gently overlapping petals, creating a fresh and graceful summer display. Slender flowering stems rise above finely divided, feathery green foliage, giving the plants a wonderfully light and airy appearance.

Growing to approximately 80–100 cm (31–39 in) under suitable conditions, 'Sunset Yellow' is particularly attractive in cottage gardens, pastel-themed borders and naturalistic planting schemes. Its open flowers provide nectar and pollen for visiting pollinators, while the elegant stems are ideal for cutting and arranging in fresh summer bouquets. Regular deadheading encourages a long flowering display from summer into autumn.

Expert Growing Tips

● Sow indoors during March or April and provide plenty of bright light after germination to prevent weak, leggy seedlings.

● Pinch out the main growing tip when young plants reach approximately 15–20 cm (6–8 in) tall to encourage bushier growth and additional flowering stems.

● Avoid excessive fertiliser, particularly high-nitrogen feeding, which can encourage lush foliage at the expense of flowers.

● Deadhead regularly and cut flowers for fresh bouquets to encourage continued blooming throughout summer and autumn.

● Choose a sheltered growing position or provide discreet supports in exposed gardens to protect the slender flowering stems from strong winds.
