What Do Garden Phlox Seeds Look Like?

Let’s first know how a seed pod looks like.  A phlox seed pod is a round welling flower-like pod that contains the seeds inside.  The thin-looking pods do not contain the seeds, rather the fat-looking ones.  The seed pods are few in each flower head so the majority is not seed pods.

The seeds when dry are brown in color and oval in shape.  They easily come off the dried pods without much effort.  Once you remove the dry pods, you can store your seeds in an envelope bag rather than a plastic bag.

A plastic bag attracts mildew while the envelope keeps them dry at all times.  You may also opt to put them in a container and add some rice to keep them dry for a longer period of time.

Harvesting Phlox Flower Seeds

Before you harvest your phlox, be sure to follow these steps to enable you to get mature seeds.

Step 1:  At the end of summer, leave your phlox blooms to remain on the plant after the flowers fade. Choose healthy blooms in order to get healthy seeds.

Step 2:  Allow the phlox to continue growing until the petals drop off and the seed pod that is located behind the petals shrivel and turns brown.  Again, don’t leave the pods for too long as the pod may break and spill the seeds on the ground.

Step 3:  Cut the seed pods from the plant and put them into a paper sack. Place them in a warm, well-ventilated place until they are completely dry.  To test if the seeds are dry, they will break when you poke them with your fingernail.  If you notice they are soft, that means they are not dry enough.

Step 4: Remove the pods out of the plastic bag and break open the pods. Pick out any large pieces of leaves, stems, or petals and discard them.

Step 5:  Place the phlox seeds in a paper envelope for storage. Remember to write the name, date, and color of the plant on the envelope.  This will give you an idea of what type of seeds you have next season you want to plant them.  Store the seeds in a dark, well-ventilated spot until the next planting season.
