2.Calendula Officinalis (Pot Marigold)
When the flower closes, slowly the seeds will start to form ( all the little curls you see on the photos are seeds). Once they are dry, wrap them in paper and save them in a dry place.
If you leave calendula on its own, it will drop its seeds on the soil around it and new sprouts will come out! You can then transfer the seedlings elsewhere in the garden. It will save you time and effort to grow new plants!
