Larry your butterfly ginger has self pollinated with the help of bees or moths. The seeds are ready to harvest now. After that? Kabby has not a clue, I've never planted the seeds before! I did a search though and here is an article from Plant Delights about planting them.
"Hedychiums are relatively easy to propagate via seed. Seed should be collected as the seed pods open in the late fall. The seed should be sown immediately and grown indoors where they may take several months to germinate. Surface sow the seed and cover with a thin layer of perlite. Place the pots in a warm location and cover with clear plastic to keep in moisture and heat. Hardy ginger plant seeds will germinate best at 70-75ºF. After germination, transplant the seedlings into individual pots and keep them warm, moist, and well fed. Seedlings will grow fast and can be transplanted into the garden during the next warm season. Remember that hedychium seedlings will not be clones of the parent, and hybrid seed will rarely be as nice as the parent."
I collected many seeds the last 2 yrs for my trade group, they are usually ready in Nov.
