@Passionate4gardening Thank you for your kind words and I am glad my post was useful.

So my question is, if the seed is not dormant, would that have any effect on cold hardiness of the seedling? If so then would it be more or less a factor than everything else. Meaning if there are three factors favoring cold hardiness and one factor favor not, most of the seedlings would then have a descent chance of surviving the winter. Or of course you can flip it the other way towards a less likely survival. Do we know if any of these factors weigh more heavily than another?


My answer is going to be both simple and complex - I do not think it is known whether seeds which have altered dormancy also may have altered cold hardiness. That is the easy part of my answer. The more complex part of my answer will take a little time as I will have to do some searching for what is known about the seeds of other plant species.

Would my chosing to proceed with only non dormant seed be a bad idea considering my location. I think our last frost date is end of May and first frost maybe October. I would have to check so dont hold me to that but essentially most of the year is not growing season.


The answer to this part of your questions is also I don't know and I suspect that there may be no research on any plant species that may provide an answer, but I will look.
