Underground?
I thought it grows in the tree.
Btw where can be peanuts found?

That is so weird that they grow underground! I never knew that before. But i guess it makes sense when you look at peanut shells they are 'dry/earthy' feeling sort of like potatoes (due to being underground).

Our Former president Jimmy Carter came from peanut country

"Peanut seeds (kernels) grow into a green oval-leafed plant about 18 inches tall which develop delicate yellow flowers around the lower portion of the plant. The flowers pollinate themselves and then lose their petals as the fertilized ovary begins to enlarge. The budding ovary or 'peg' grows down away from the plant, extending to the soil. The peanut embryo turns horizontal to the soil surface and begins to mature, taking the form of the peanut. From planting to harvesting, the growing cycle takes four to five months, depending on the type or variety."

And from a 2nd source: "After pollination, the fruit develops into a legume 1 to 2 inches long containing 2 to 3 (rarely 1 or 4) seeds, which forces its way underground to mature"

So.... Uhm... Underground and they're actually seeds.... from what I think I understand.

I'd always wondered where peanuts came from. Another thing I've wondered is how peanuts come in mass quanitities without the shells. How do they get the shells off?!
