Sulphur Red Cosmos flower Seeds are excellent for cutting with a vase life of 7 - 10 days. Cut the blooms in the early morning hours, and select stems with flowers that have petals just beginning to unfold.
The bloom will fully open once in the vase. Remove the leaves below the waterline,
Directly sow Cosmos seeds into prepared soil after the danger of frost has passed. The flower seeds can be scattered and lightly raked under at a depth of 1/16 inch. Keep the flower seeds moist until germination, and blooms will appear in about 10 weeks.
