Ginger

Almost anywhere you go in a slightly mixed coniferous/deciduous forest in the valley right now, you will run into mats of the plant Asarum caudatum or wild ginger.  It's not too spectacular of a plant in itself, but it does have an interesting flower that you don't notice unless you turn some leaves over and look around a bit.

While it's common name is wild ginger, I wouldn't say it's anything like what you buy.  If you crush a piece of root  - which is small - or a piece of stem which grows along the ground there is a distinct gingery/citrus smell and taste.  Grizzly1
