While not included on the U.S. endangered species list, the Venus Fly Trap is included on the protected plant list in many states where they grow natively. The best way to harvest a Venus Fly Trap is to collect its seeds, which form from the flowers in the early spring, and use the seed to start new plants. This can be done with plants in the wild and with domesticated indoor plants. Before collecting any seed from wild plants, contact your local conservation department to be sure that it is legal to do so in your area.
Begin watching the Venus Fly Trap in the early spring. Small stalks will appear that have tiny flower heads.
Look for the seed pods to appear after the plant flowers. This can happen as early as April in the deep south or on indoor plants and as late as June in the upper areas of the native coastal areas of the plant.
Cut the seed pods from the plant using sharp scissors. Place or let them drop into a small bowl or cup.
Break apart the seed heads to remove the small seeds inside. Do this gently.
Spread the seeds on a layer of newspaper and leave them to dry in a well-ventilated area. This will take two or three days.
Store the dried seeds in a sealed envelope until ready to plant.
