Sulphur Orange Cosmos is 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 waterline, and enjoy a beautiful bouquet.
Directly sow Sulphur Orange 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.
