I’ve been thinking about this ever since I saw the Hunger Games movies (the first two) and read all three books. I wondered if there really was an edible tuber called Katniss. Guess what? There is. You can learn about this plant: what it looks like and how to grow it at this link: http://www.gardeningknowhow.com/ornamental/water-plants/katniss/growing-katniss-plant.htm
Other edible tubers including many that grow in or around water can be found at:
I don’t live in a place where I can grow anything, but as we travel around, if some of you who have the property with which to grow them will keep in touch, you can share your recipes with me, and perhaps invite us (just my husband and myself) dinner and we can try them out. We love meeting new people. Depending on where we are staying, we may be able to reciprocate the invitation.
If you have tried any of these let me know. Of course I know about blueberries, mulberries, and artichokes (not the Jerusalem ones). Personally, I never met a berry I didn’t like.
Happy discovering and eating. God bless.
