A very beautiful variety of shorter cosmos, with flowers that open the darkest, most luscious crimson and then fade a little to look antiqued. Unusual and lovely.
The brilliant thing about this one is, with shorter stems, it doesn't need staking, and is perfect for pots.
Cosmos last 10 days in the vase, produce at least two buckets of cut flowers a week from a 1 x 1m patch and do so from late June until November – so that's nearly fifty buckets of flowers in one season from a small patch. They are impossible to beat.
Pinch out tips at 15-20cm to encourage bushier plants. Stake and tie Cosmos plants if necessary during the growing season, water regularly and dead-head to prolong the flowering season.
