Collecting and Growing Celosia (Cockscomb) Seeds

Harvest: Wait until flowers dry on plant. Shake or rub over a white plate; seeds are tiny, shiny black.

Indoor winter growing: Possible but not ideal. Cockscomb needs strong direct sun; winter light is weak. If attempted, use grow lights and warm temperatures.

Best to store seeds cool/dry and sow outdoors after last frost.
