To start, I know paperbarks are difficult to propogate, that you'll only get a 5 to 10% germination rate from seeds. I've also read that most samaras will be empty if you crack them open hence the difficulty. So I have a question about the samaras I picked from my tree. I have a very large bag I'd put in the freezer. I thawed them yestereday and this morning cracked open 5 or 6. Had they all been empty or dried up and shrivelled I was going to toss the bag. Well, none were empty, 4 of them had bad seeds but two were plump and green inside. I don't know, am I defying the odds or is it the green, plump seeds that actually get the 5 - 10% germination rate? Here's my picture. You can see a couple of the dried up tiny seeds and the two beautiful green ones in the pod and some of their pieces on the tissue.
