Did y'all know that yellow nutgrass (Cyperus esculentus) has edible tubers often called earth almonds because of their almond like flavor. They can be eaten either raw or cooked. Their sweet, nutty flavor makes them ideal for a bunch of different recipes, from soups to sweets. I didn't know if anyone knew or was interested in knowing but I figured I share that with everyone. Next time you pull some nutgrass out of your garden try some of the tubers and get some use out of those pesky weeds.
Purple nutgrass (Cyperus rotundus) can also be eaten but smells and taste like vics vapor rub smells.
