My son S. and I noticed a bag of raw peanuts in the pantry one morning after breakfast and decided to put a few of them in a potted plant in the house to see what would happen. This was back in late January and we kind of forgot about it.
Quite a while later, perhaps 3 weeks or so, we noticed the new growth in the houseplant. One of our peanuts had come up!
We transplanted it into a one quart pot for a couple months where it grew slowly but surely under the lights in the seedling room. Then we finally got it planted outside in a 6 gallon square pot with about 14 inches of foot space to grow in. I don’t know what we’ll end up with, but I’ll be disappointed if there isn’t at least one nice peanut pod growing under this thing when September or October comes.
Peanuts aren’t the only thing you can grow from “normal” grocery store food. Almost every type of bean can be done this way, and the spice aisle can be sprouted for mustard, celery, cilantro (coriander) and more.
