Millet, Sorgum, Smart Weed.
If you can Find it, Wild Rice.
I had a website 2 years ago, that sold Wild rice to plant. They got hit by a Hacker and their Site got Wiped out. I didn't save their Address or Phone Number, WISH I HAD!
Wild Rice is VERY EXPENSIVE to buy to plant!
I have a Feed Store near me, the owner did some Tracking Down of some places to buy Wild Rice Seed, Avarage was $300.00 for 25 pounds of seed!
If you can Find a place that holds major consentrations of Duck Weed, Skim it and put it in Plastic Bags and Transplant it!
I'm Sure there are many other seeds and plants you can get and plant, those are just a few I have delt with!
Our youth are the Back Bone to hunting of the Future. Teach them WELL!
