New to me, grown from seeds from Prairie Moon Nursery https://www.prairiemoon.com/osmorhiza-longistylis-anise-root 

A lacy, spring blooming species for partially to fully shaded gardens and ecosystems. The anise scent, and flavour, suggested int heir common name extends to their foliage, which is edible and can be used as a flavouring or nibbled on its own.
