Perennial primroses come in a range of varieties and colours. They produce small, dainty flowers nestled amongst deep green foliage. Once the flowers begin to fade, the primrose begins producing seeds. While the primrose readily self-seeds itself, you can collect the seeds so that you have control over where new plants grow in the garden. Seed heads usually mature in late summer. You must keep an eye on the plants, as the pods split open when mature, scattering the seeds.
Cut the flower stem from the plant at the base once the primrose pods turn brown and dry. The stems bend toward the ground as the seed matures, so examine the ground around the plants for mature pods.
Place the stems in a brown paper bag, with the pods resting on the bottom of the bag. Put the open bags in a warm, well-ventilated room for two weeks so that the pods can finish drying.
Hold the pods over a bowl and split them open with your fingernail. Shake the seeds out of the pod and into a bowl.
Label an envelope with the primrose variety, colour and year harvested. Place the seeds inside and seal it.
Store the envelope in a cool, dry room until you are ready to plant in the spring. Alternately, place the envelope in a jar and store it in the fridge.
Primrose seeds remain viable for up to two years.
Hybrid primrose varieties may not produce seeds true to the parent plant.
