How to Sow and Plant

Sow seeds directly outdoors after the last frost, or start indoors 4–6 weeks earlier.
Cover seeds lightly — cosmos need some light to germinate (surface or very shallow cover).
Keep soil moist until seedlings emerge. Thin/space to 12–18 in apart when established.

How to Grow

Position in full sun for best colour and flower density.
Use well-draining, average garden soil.
Water moderately; plants are heat/drought tolerant once established.
Deadhead spent flowers to prolong blooming.

Tips

Start indoors for an earlier display; thin seedlings to avoid crowding.
Support very tall varieties if you want cut stems — otherwise they naturalize as airy borders.
