Impatiens are prized as a bedding and container plant because of their long blooming season, easy care and range of colors. They thrive in partly shaded areas of the garden where few other bedding flowers grow and bloom successfully, bringing color to areas otherwise left bare. Collecting impatiens seeds allows you to propagate your favorite varieties and colors without worrying if the seed suppliers or nurseries will continue carrying it from year to year. Impatiens produce seed pods that explode once the seeds are ready, so it is necessary to plan ahead or the seeds will be scattered to the wind.
Stop pinching of the flowers once you are ready to collect seeds. Let the best looking and healthiest plant set blooms and seed pods unhindered.
Cut a 5-inch square out of cheesecloth. Wrap it around the seed pod like a bag and secure to the stem with a paper clip.
Wait for the pod to start to become translucent. Let the pod burst open naturally, or begin touching it through the cheesecloth daily until it bursts open and releases the seed.
Remove the cheesecloth bags, being careful not to spill the seeds which are very small.
Place the seeds in a shallow bowl and set in a dry room away from any drafts or breezes that may scatter the seeds. Let dry for one to two days.
Place seeds in an envelope or sealed jar. Store in a cool place such as a refrigerator.
