water and a teensy bit of rooting hormone... might help... couldn't hurt at any rate.
I too have this same issue. I planted some in pots and will just leave them. Also I am going to put a few in the veggy garden and wait. Could be what they are needing to pop. varying in temp humidity, may help. I really want these things to sprout.
I may just have to make my work buy some.
Thanks for the update

Step 1
Separate your dormant seeds from those which are sprouting. Typically these are the ones that have not sprouted in the seed starters for two weeks or so after the others have begun to.
Step 2
Prepare your potassium nitrate solution. Though you can use it straight, scientific studies show that there is little, if any, change in effectiveness if a solution of ¼ to ½ tsp. per quart of water is used.
Step 3
Apply the potassium nitrate solution to an absorbent pad, or pour it into a jar. The pad is useful for a lighter treatment and when immediate planting after treatment is not possible. The jar provides a stronger jolt and requires immediate planting after treatment.
Step 4
Stir the seeds daily if using the jar method. A day or two of soaking should suffice, after which the seeds should be immediately replanted without drying or rinsing. If you're using the absorbent pad, seeds can be allowed to remain until germination just begins; then they should be replanted.
Step 5
Wait patiently for the seedlings to emerge. In some cases, this may take up to one month after treatment and it will vary by species. Proceed with normal care after germination.
Root cap, don't remember if you had simply planted some and let them sit for a few weeks. I am doing that now with both Mikado and Acapulco gold that seem to not want to pop. Mikados are only afew years old and the Aca Gold I think closer to 12-15yrs. Both are going to be given a go here today. I have seen this happen as mentioned before by others. Sometimes just letting them hang can break that dormancy. good luck
