Nepeta cataria is the scientific name for catnip. Catnip is a plant that is easy to grow. If you have cats in your home, you may want to grow this plant so you can make your cat a snack or some catnip toys. One way to do this is to harvest the seeds from the catnip flower and enclose them in a little pillow or ball. Removing the seeds from a catnip plant is fairly simple.
Let your catnip flower dry out on the catnip plant. This will happen at the end of the season.
Cut the flower off the catnip plant with a pair of scissors. It is best to cut the flower off, rather than pull it. This is because the seeds will be dried out and any sudden movements could cause them to fall out.
Hold your flower over a paper plate. Turn it upside down and give it a few shakes. The seeds will come loose and land on the paper plate.
Use your fingers to spring loose any remaining seeds that did not come out when you shook the flower.
Transfer your seeds to a plastic storage bag until you are ready to use them.
