You can plant some now in their own special area in the garden so you can keep track of them. When they come up in the spring they put up just a few leaves from the base the first season. The next year they should put up a stem and then a bloom the third year from starting. These aren't hard and fast rules, sometimes when very well grown they may bloom the second year.
As a backup, collect some bulbils and store in the crisper in a ziplock bag with peat moss or wood shavings with no more than a couple drops of water to keep them hydrated. Check on them from time to time during the winter. These stored ones can be planted out in the spring.
What you don't want to do is leave them laying around drying out because they are not real "seeds". They are small bulbs that need to be kept hydrated until planted.
