This plant is often confused for Sweet Cicely, but that plant is Osmorhiza claytonii. This one has has a stronger anise scent and more flowers in its umbellet than the O. claytonii.

My personal experience with the Aniseroot is a good one. Several bare roots were planted last fall under a Scots pine on the east side to give them the dappled light that they prefer. Other than when they were first planted, the only water they have been given is rain. They exploded and are currently flowering. I look forward to their interesting seed heads.

This plant attracts a variety of small and medium pollinators and is a host plant for the Black Swallowtail butterfly.
