How to Grow:
Start seed indoors in trays 4-6 weeks before last frost; transplant out after all danger of frost has passed. Cosmos can also be direct seeded once weather has warmed.
Individual blooms don’t last long in the vase, about 4-6 days, but each stem is loaded with multiple blossoms that open over a period of a week. Harvest when flowers are just starting to unfurl, but haven’t fully opened in order to prevent insects from pollinating, which will help stretch the vase life by a few extra days. Flower preservative is recommended.
