Wait for the seeds to dry out on the dusty miller plants at the end of the summer. Stop watering them a few weeks before you plan to harvest the seeds. This way the seedheads will dry out completely while still attached to the plants.
Remove the seedheads from the healthy Silverdust plants. Shake the seeds out into a brown lunch bag. If the seeds don't come out with a hard shaking, you may need to crush the pod manually and extract the seeds with your hands.
Toss a silica gel packet inside the brown lunch bag to keep the bag free from moisture.
Fold down the top of the lunch bag and place inside a glass jar. Tighten the lid and set the jar in a cool dry location until spring.
Known hazards: The plant contains pyrrolizidine alkaloids which are highly toxic to the liver, so the plant should not be used internally.
