Seeds can be harvested at the end of the season. Not every flower will produce seeds. Seeds should be throughly dried and stored in an airtight container.
The seeds have a hard shell and will benefit from scarification or soaking in water overnight before planting.
You can direct sow the seeds after frost danger is over or start indoors 6 to 8 weeks before planting outdoors.
