I just harvested my plants Saturday and lastnight I put a couple in a papertowel and one split open the other has not yet. I would think what keeps them dormant till the next spring is that is just to cold get the juices inside doing what they need to do to germ. I tossed the underdeveloped ones that looked like acrons and the yellowish ones and kept the camo looking ones. Dig a couple out and germ them also becarefull when moving your plants around the seeds well fall out I lost a few not realizing what the hell I was doing.
