"If your literature is credible and the majority of seeds sprout unexpectedly, then I would wonder if the seed was correctly identified in the first place. "
>>> I know the seeds are identified correctly because I grew them myself. That is the difference in the seeds- they were mine (not from a commercial source), handled and stored appropriately, and sown relatively soon after harvest. Seeds are don't seem to develop that hard-to-overcome dormancy for a while after they're harvested. Sown fresh, I think most anything sprouts easily.
