Anyone have any experience with bigleaf maple seeds? They are the largest native maple here in the Pacific Northwest. The seeds don't fall until late summer into the fall. I have noticed that some years the trees don't produce a lot of seeds but most years one tree produces tons. Just my neighbors big leaf maple which is at least 100 feet away from my house can produce enough seeds to still block my rain gutters.
One issue I see with the bigleaf maple is that the seed coating has a bunch of fine hairs on it that will stick in your skin if you handle them. I was collecting a bunch to broadcast over an area I was wanting volunteers and I kept getting the hairs stuck in my fingers. Same thing happened when I walked barefoot over them. Anyone have any experience removing the seed coating? Could be fairly slow going... I wonder if putting them in an oven or solar dehydrator first would cause the seed coating to open up. If it did then it could be fairly easy to remove the coating. Once that was done you could roast the seeds.
I'm assuming the bigleaf maple seeds are edible - I know the flowers are. Anyone able to confirm?
I did a quick google search and on the site "Plants for a Future" they list the seeds as being bitter but apparently one option is to sprout the seeds and then eat the young sprouts which apparently have a nice flavor. Here is the site:

Reading this report from the USDA:
https://www.plants.usda.gov/plantguide/pdf/pg_acma3.pdf - it seems like getting the seeds to sprout could be challenging since you need to stratify the seeds for a few months first. Though it does sound like you can collect the seeds when they are fully developed but have not dried yet and they will sprout without the stratification. That might be an option - there are normally a ton of seeds on a single tree but I wonder if it would be worth while as a food crop...
