Cosmos bipinnatus is a frost-tender annual that thrives in full sun, making it a perfect choice for warm, sunny spots in the garden. Seeds sprout within 7–14 days when sown at a depth of 1/8–1/4 inch in soil kept at an ideal temperature of 70–75°F. Plants should be spaced about 10 inches apart to allow for their bushy growth habit and will reach an impressive height of approximately 3.5 feet.
This easy-to-grow variety adds height and charm to garden borders, cottage gardens, and wildflower meadows. As it is not frost-hardy, it is best planted after the danger of frost has passed, ensuring a vibrant display throughout the growing season.
These cosmos flower seeds are available directly from Garden Faerie Botanicals in the heart of British Columbia, Canada. The collection features heirloom and heritage seeds that are personally cultivated organically without the use of any chemicals. Emphasizing historical, rare, non-GMO seeds, this selection preserves biodiversity through open-pollination.
