Included in C. thalictroides in Michigan Flora.
Rich deciduous forests.
Blooms earlier in the spring than Caulophyllum thalictroides, and then readily recognizable because the young foliage is a dark purplish green, with the flowers a dark blue-purple. Despite the name, this and C. thalictroides are roughly the same size when the leaves are fully expanded.
