Cosmos ‘Double Dutch Rose’ Seeds
(Cosmos bipinnatus) – 30-35 Seeds

Direct sow outdoors after danger of frost has passed or start indoors 4–6 weeks early.
Cover seeds lightly with soil and keep moist until germination.
Prefers full sun and well-draining soil.
Avoid overly rich soil, which can encourage foliage growth over flowers.
Deadhead or cut flowers regularly to encourage more blooms.
Annual; blooms summer through frost.
