I've been harvesting these seeds today and have collected spent blooms on several days over the last 2 weeks. Today I went about removing the chaff and plant material from the seeds and found that some seed heads were very easy and others had spent petals attached rather firmly. The latter were hard to do and I finally gave up. The others I could just rub my finger over the seed head and remove all the chaff to be left with just the seed head on the stem. I then could firmly rub the seed head and the seeds would fall apart into my collection bowl. Anyone have a specific time period that they allow the heads to dry that makes them just right as described? I think the difficult ones were dried too long so that the seeds fell out along with all the material...made sorting too difficult.
