Cosmos bipinnatus 'Purity'

Plant details

A pure white form of this popular border annual that flourishes in full sun, cosmos prefers moist but well-drained soil. Regular dead-heading encourages continual flowering, and from June to October the large, graceful, saucer-shaped flowers are handsomely offset by the masses of mid-green feathery foliage. It is advisable to stake early in the season. Cosmos make good cut flowers and are an excellent addition to the cutting garden.
