New to me, grown from seeds from Prairie Moon Nursery https://www.prairiemoon.com/amorpha-canescens-lead-plant-prairie-moon-nursery.html 

A semi-shrubby perennial, this is a species that I would suggest as a native alternative to Russian Sage since they are suited to similar ecological niches and plant communities, attract lots of pollinators and have a similar overall aesthetic.

Please check out the Prairie Moon listing at the link above for more details.
