How to Grow
Cosmos seeds should be directly sown into prepared seedbeds outdoors after all danger of frost has passed. For a natural setting, the seeds can be scattered onto the prepared soil. Lightly rake the soil over the seeds at a depth of 1/16 inch and keep the area moist. Under proper conditions, these seeds will germinate in 14-21 days. These plants will self-sow and return the next year if some spent blooms are allowed to remain on the plant. However, deadheading will prolong the bloom season for the current year.
- Environment: full sun
- Soil: well-drained w' 6.1-7.4

Cosmos (Cosmos Sulphureus Orange) - Drawing butterflies and compliments alike, these brilliant orange Sulphur Cosmos add a splash of color in any setting. Easy-to-grow flower seed will produce blooms in only 10 weeks! This variety stands out in the border and produces an abundance of 2 inch semi-double and double orange blooms all summer long. A sunny location and little water is all the plants need to perform well. Don't even apply fertilizer as it tends to produce unusually tall, lanky plants with few blooms. These flowers are commonly called Klondike Cosmos.
Sulfur Cosmos are known as an excellent cut flower with a vase life of 7 - 10 days. Cut the blooms in the early morning hours, and select stems with flowers that have just opened. Remove the leaves below the water line, and enjoy a beautiful bouquet!
Directly sow Klondike Cosmos seeds into prepared soil after danger of frost has passed. Lightly rake the soil over the flower seeds at a depth of 1/16 inch. Keep the area moist until germination. The plants perform well even when crowded.
