I think some were English oak, and some were Garry oak, and some were hybrid reds. I gathered them over a period of a month in the Pacific Northwest. I was working and didn’t have refrigerator access . Some did fine ( most of them were gathered at the end of the trip.)
I had quite a diversity of them, it’s disappointing but hey, one has to learn some how.
I will have a cooler with peat moss next year.
The ones pictured below are the ones that sank!
