Karl asked "how to separate the tiny seeds from all the chaff" Suggestions I have tried out with some success include a sieve and a gentle air flow. I use a kitchen sieve intended for sifting flour. Some seeds fall through while the larger pieces of chaff are caught. I have a few other mesh sizes from a plastic mesh bag, some tulle fabric, and a pasta colander which work with various seeds. The tulle fabric I hold tight between two plastic strawberry baskets. Then to remove the lightest bits of chaff, sometimes it works to swirl the seeds in a bowl while gently blowing over the surface. Another technique is to pour the seeds and chaff back and fort between two paper envelopes. The seed tends to roll out first so each time I tap out the left behind chaff in one envelope then pour back into it until the proportion of chaff is very low. Then, finally, there are the tweezers for those last few bits. Then to pour the seeds into a tiny envelope I place a funnel in the envelope, holding the funnel upright with a jar, and pour the seeds into the funnel. It it tedious and does not always work so well. I hope someone has perfected a much easier method because the way I do it is tedious and messy. In summer 2012 I made a couple short videos of the process. part 1: Sieve http://flickr.com/photos/gastils_garden/… part 2: Tulle fabric http://flickr.com/photos/gastils_garden/… I expect I miss-pronounce the genera. I only read them; I do not hear them said aloud. I once asked an expert on native flora how to pronounce Sisyrinchium and he said "confidently". - Gastil
