Answer: Artichoke seeds can take some time to sprout and they really need a cold stratification to sprout well. I don't know if your seeds were treated prior to being packaged or if the seeds are old (look for a packaging date on the seed packet). To check the viability of your seeds, place a couple of them between a dampened, folded papertowel, set them in a plastic baggie and put them on your kitchen counter. With a few more seeds, place them in a baggie with a moistened papertowel and put them in your refrigerator for about 45 days, then sow the seeds. See which seeds sprout first. Then you'll know whether or not your seeds need a stratification period.
You should be able to purchase artichoke plants in your local garden center. If not, I hope your seeds are successful!
