Menzies' Larkspur, Delphinium menziesii

These pretty blue flowers were found growing along Fly Creek in SW Washington.

Tall Pepper-grass, Lepidium virginicum

This non-native annual is growing on  a rock outcrop at Lucia Falls County Park in SW Washington.

Sharp-Toothed Cinquefoil, Potentilla arguta

Yet another resident of Lucia Falls County Park in SW Washington, this thornless member of the Rose family is not commonly found West of the Cascades.  I found quite a few growing in a sunny, rocky area with very little soil.

Enchanter's Nightshade, Circaea alpina

I have no idea why, but this plant decided to show up on our property in SW Washington 2 years ago and now there are hundreds.  It is a small understory plant that can form a dense community on the forest floor.
