I work with Gossypium (cotton) and when i recycle soil from failed germinations, i also get seedlings appearing months later.  Even various herbs are emerging in pots i re-used.

 The subject of delayed germination
 was mentioned a few days ago, so I am offering a couple of
 examples from my yard (which includes the driveway, lawn,
 garden beds, shrub areas, gravel walkways, firewood storage
 area, potting shed, and clothes drying area). 
 A few years ago I bought Cyclamen graecum seeds from the PBS
 seed exchange. They were potted out, nothing happened for 3
 years, so I tossed the pot contents one summer day when I
 was cleaning up the seed pot area 2 years ago. This year, 3
 seedling leaves appeared where the pot was tossed, making
 this five years from start to appearance of new seedlings.
 Not sure they'll survive the winter, however, as we've had
 two rounds of snow and temperatures into the mid to low 20s
 (F) so far. If the leaves still look good after the next few
 storms blow through, I will pot up these seedlings and put
 them somewhere a bit more protected. At least, I think these
 are Cyc. graecum. The leaves are a very different shape from
 the Cyc. hederifolium and coum seedlings I have elsewhere in
 the yard, but ants drag seeds of the former species all
 Then, four years ago, a friend gave me some old Erythronium
 hendersonii seeds. I sent most of the seed on to the PBS
 seed exchange, put a few in a large pot, and waited.
 Nothing. Last year, one seedling leaf appeared. I scrape the
 moss off each year, add fresh gravel, by the way. This week
 I was checking the pot and saw dozens of tiny leaves
 emerging all over the surface. I do not recall how many
 seeds I planted. But it is clear that it took them a few
 years to decide to germinate, perhaps indicating that the
 seeds were fairly old. 
 Gardening, and growing bulbs from seed, seems to be all
 about patience.
