Growing Notes

Transplant (recommended) - Sow into 72-cell flats or preferred seedling container 4-6 weeks before planting out. Do not cover seed as light is required for germination. Harden off and transplant out after danger of frost. Bottom water or mist to avoid covering seeds. Direct seed - Where summers are long. Once established, prefers well-drained soils and temps of 70-75°F (21-24°C). Plants may need support. Pinching is recommended to encourage uniform and productive branching.

Harvest

Cut when 2-3 layers of petals have unfolded but before flowers fully open to reveal center. Expect a vase life of 7 to 10 days. Harvest or dead-head regularly for optimal yields.
