I bought Sheep's Bit as a small plant and planted it in the spring. It bloomed nicely all summer, did not grow too aggressively, very pretty. As the flower heads dried I saved them for seed. Can somebody tell me what the seed looks like? I've got small twig-like particles and also some more chunky-looking particles with "wings" or "strands" attached. Are either of these the seeds? Since it was already a plant when I bought it, I didn't see the seeds and I didn't find a photo on the seed site. Thanks for any help.
