Just plant some and see how many sprout??
My favorite ironies are watching people who decide to buy organic food, buy in bulk and then throw half of it away after it spoils several days later. Then they begin buying the 'other' organic brands because they have a longer shelf life. Go figure.
I ain't falling for that again. Someone told me if I planted Cheerios I could grow my own donuts. They NEVER came up! ;-)
