If you have a shaded or partly shaded area that needs a little visual interest, you're looking at the right plant. Its flowers are on the small side (lovely, though, if you get really close), but meadow-rue has distinct lacey foliage that looks very similar to the foliage of columbine (they're closely related). The delicate leaves contrast well with miterwort, western coneflower, heartleaf arnica, and large-leaf avens. 
 
 
 
In the wild, meadow-rue grows in moist forest understory and along streams, so in the garden it will appreciate fairly regular irrigation. The more sun it gets, the more water it should get. Meadow-rue is a good option for sprinkler overspray areas or gutter downspouts.
