How to grow
How To Grow Cosmidium From Seed: Grow Cosmidium in a sunny setting. Deadhead spent blooms to prolong flowering and encourage continuous blooming. Leave a few plants to die down and self seed. Do not over fertilize as it will cause a decreased number of blooms.
Sow Cosmidium flower seed directly outdoors after frost season has passed. Prepare a seedbed, soil should be fine and weed free. Sow Cosmidium seeds in rows 18 inches apart, 6 seeds per foot. Keep soil moist. Thin seedlings to strongest plant, 18 inches apart. Carefully replant the thinned seedlings.
- Sowing Rate: 2 - 3 seeds per plant

Flower Specifications
For best results, provide a well-drained soil in full sun. When large enough to handle, transplant seedlings into 3 inch pots or trays. Gradually acclimatise young plants to outdoor conditions for 10 - 15 days before planting out after all risk of frost, 9 - 12 inches apart.
