If you plant berries or (green seed) in the fall, it will not come up the next spring (in most cases), but will most likely come up the second spring.
There are exceptions to that, but as a general rule that is how it works.
There are some ginseng plants that produce red ripe berries very early (like June or early July) and I have seen video evidence that those that produce berries really early, will often germinate and produce 3 leafers the next spring.
I have also planted stratified seed in a bed, and saw the large majority of that come up the next spring, but then again in the next spring after that more come up. At times it can delay for a year or even two and then still germinate.
This some what random oddity in how it does this occasionally has probably helped it to survive for so long.
