No idea yet... I did find another blog article mentioning it. It's a SU (normal sugary) hybrid, best eaten the day it's picked. Everything is done for transportation and storage quality now, which probably explains why it was abandoned. The author in the article said it could still be found infrequently, but made no mention of where.
Googling this by name is hard, since there are so many articles that come up about Native Americans instead!
I used to grow Seneca Chief in Michigan. It's in a class of its own in my experience. I tried it here in Virginia, but it wasn't the same. But I want to try it again. There supposedly is a source in Canada - I'm trying to find out what their seed source is. It's the theseedhouse on Etsy. This variety should be brought back! Another plant that should be brought back is the Fairfax strawberry (in my opinion).
Hate to say it but corn doesn't get the same attention I think as other heirloom plants. Probably because it's so easy to hybridize. It was the first thing that came to mind when as I read through this.
Has to be sweet-if it's not, might as well be field corn.
Has to be productive-what good is it if it doesn't yield?
Slow converter from sugar to starch.
Early vigor.
So far, Aces is the best I've found. Non-GMO hybrid.
