I have a few thousand seeds I didn't get planted because the weather got bad early. So I have them in the fridge and am going to try to get them in the ground very early spring. So a couple of weeks ago on my weekly moisture check I saw that one seed had put out about an half inch long root, so I stuck it in a cup of dirt and put it on top of the fridge (a little warmer there than most places). Here is a picture of how it is doing.
