- Habitat: Moist forests, meadows, streambanks, and ditches.
- Pair with: Western redcedar, twinflower, mountain sweet cicely, red columbine
- Fun Fact: This attractive groundcover is an indicator for forest soils with above-average moisture and nutrient levels. At low elevations, it has three distinct leaflets on each leaf, but at higher elevations the leaflets join to become one leaf with three lobes.
