Not only is it good at attracting monarchs and other pollinators, it also happens to be very showy!
Meadow blazing star has a large and patchy range in the midwest and great plains. This blazing star is quite similar to rough blazing star (Liatris aspera) but tends to be taller, and its flower heads are larger and on longer lateral stalks which gives the whole spike/inflorescence a more branched look.
