Blue-stemmed Goldenrod (Solidago caesia)

$5.00

Blue-stemmed Goldenrod is probably my favorite Goldenrod. Plus, it has very high value to pollinators, especially the specialists. The nectar and pollen of the flowers attract a wide variety of insects, especially native bees (illinoiswildflower.info). It is also the host plant to 135 species of butterflies and moths in our area (nwf.org) as well as the host to an incredible 43 specialist bees (Holm, 2017) (Johnson and Colla, 2023). It is also great to have an option that blooms in the shade! Goldenrods in general provide so many ecosystem services even when most other plants are shutting down for the season. Just something to keep in mind, goldenrods do not cause hay fever! Their pollen is too heavy, it is the wind-pollinated (but not as visually obvious) ragweed that causes it.
