The Versailles series have been bred specifically for cut flower production; they are best white-flowered cosmos variety with long, straight stems and large, clear blooms. 

Sow under cover four weeks before your last frost date; sow outside after the risk of frost has passed. Sowing temp 18-21°C; germination between 5-10 days in optimum conditions. Pinch to encourage branching. 

Cut when the petals are just lifting away from the bud - also called the 'cracked bud' stage. Vase life declines quickly if the bloom is pollinated prior to cutting. Place immediately into water; no special conditioning required.

Vase life: 5-7 days
