I'd bought some dried Mimosa P. that was gritty and tasted like straight up dirt! And I'm used to nasty stuff .... Then when I tried growing it, the seed sent turned out to be some variety of red amaranth. Phooey! Then I got sidetracked ...
One thing that's easy to grow is Papaya trees... I started some in pots a few months ago and they're doing good. I don't know just how beneficial this is, but I take the dried up seeds and grind it into a "Papaya Pepper". It's good to sprinkle on some dishes. Ehh
