Cultural Notes:
Blue-stem Goldenrod (Solidago caesia) is distinguished by a smooth, purplish-blue stem (more so with age) and flowers that are found in clusters along the top half of the stalk, creating small, graceful, arching sprays. This goldenrod is perfect for part shade areas and pairs well with Southern harebell (Campanula divaricata) which blooms around the same time.
A species with similar flower arrangement is Zigzag Goldenrod (Solidago flexicaulis) but that is much less common and has wider leaves.
Contrary to popular belief, goldenrod is not a source of fall allergies because its pollen is not light enough to be transported on the wind. Goldenrods are insect pollinated and highly sought after by native bees and butterflies for pollen and nectar. Fall allergies are associated with wind-pollinated plants such as ragweed (Ambrosia artemisiifolia), an annual plant with greenish flowers that is often unnoticed.
