You are so very welcome! The seed doesn't seem to remain viable for long, so I'd say to sow when fresh. You could tie a mesh bag around the seed pod so the seeds would drop into the bag. In nature they would fall to the ground and germinate. From this site:

Seed can be sown fresh, in late summer - autumn, but in cold climates it can be kept refrigerated (not frozen) and sown in spring. It must be kept in the refrigerator or it will perish. Seed should be sown in deep (10 cm) trays, in a mixture of equal parts river sand and fine compost, and kept semi-shaded and moist. Seed germinates readily within six to eight weeks. The seed should be sown thinly as the seedlings will stay in the tray for their first year. Seedlings should be potted up into individual containers during their second year and can be planted into the garden or permanent pots in their third year. Flowering can be expected from their third or fourth year.
