Harvest Tips
Deadhead flowers regularly by pinching or cutting spent blooms just below the flower head—this encourages continuous flowering throughout the season. Cut flowers last 5-7 days in a vase if harvested in the morning when fully open. To collect seeds, allow a few late-season flowers to mature fully; seeds will dry on the plant and can be collected when brown.
