Cosmos

Cosmos bipinnatus Purity

• Position: full sun
• Soil: moderately fertile, moist, well-drained soil
• Rate of growth: average
• Flowering period: June to October
• Hardiness: half hardy annual

This popular, pure white annual cosmos makes a great filler plant for a sunny, moist but well-drained border. As long as it's dead-headed regularly it will produce a succession of graceful, pure white, saucer-shaped flowers up to 10cm (4in) in diameter from June to October and masses of feathery, mid-green leaves.

• Garden care: Stake with brushwood or ring stakes well before the flowers appear and dead-head regularly to prolong flowering.
