Bluestem Goldenrod (Solidago caesia) has a bright yellow flower that blooms late in the summer and well into the fall. Bluestem Goldenrod is an important late season food source for bees and other insects. While Goldenrods are often held responsible for fall allergies, it is in fact Ragweed that is to blame! So, enjoy this particular beauty of creation sneeze-free! Compliments other fall blooms such as the Smooth Blue Aster and the New England Aster.
