Bonsai Nut
Nuttier than your average Nut
Smoke, I just looked up Miyasama Yatsabusa and it looks like that to lol. I'm going to try to get better pictures over the weekend of the trees.
I'm going to write a post about the difference between species, varieties, and cultivars. Because your trees are from seed they CANNOT be cultivars. They CANNOT be Miyasama Yatsabusa. They might look like it... but that's about all you can say. You have three options - the species name, or one of the two sub-species.
