Wilderness Weed of the Week

Nut Grass or purple nutsedge is the Wilderness Weed of the Week. He's a survivor and will be around for a very long time. The root system and tubers provide all the ground running ability needed to cover miles and miles of pristine wilderness. The seeds are very productive also. Some say this is the number one weed in the world but that's for another days comparison.

Seeds and tubers are very easy to find for study because this guy is everywhere in most states.
