Seed Production Video

Leon Slichter picks a Common Crupina flower and holds it up to the camera lens and comments "When you first seet this you think, boy it's about ready to open up and really have a beautiful flower, but that's it right there, that's the total deal." He goes on to say the a large black seed comes out of the flower head with kind of a double winged effect on it and that's what hooks to livestock, people's clothes, ATVs, all sorts of stuff. He further explains that in the spring these are readily identifiable - as they emerge they have a real frilly appearance and where they are thick they are almost like a ground cover and that would have to do with last year's seed production. At this site, they aren't real thick - it's definitively an infestation, but they're not as thick as they see them at times.
