yellow nutsedge, Cyperus esculentus

Recognize these from your lawn? They're a little challenging to get rid of. So maybe we should just eat them? Wouldn't be anything new. This nutsedge is one of the oldest cultivated plants known, it's use dating to at least the sixth millennium B. C. The 'nuts' are small tubers on the roots. Yellow nutsedge is one of the worlds most wide spread plants, growing in every state except AK, MT, and WY, and in BC, NB, NS, ON, and QC. Lenawee Co MI, 8/11/18.
