Old Field Goldenrod (Solidago nemoralis)
Old Field Goldenrod (aka Gray Goldenrod) has an extraordinary value for pollinators. The nectar and pollen of the flowers attract a wide variety of insects, especially native bees (illinoiswildflower.info). It is 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 (Johnson and Colla, 2023). The Xerces Society also considers it a preferred pollinator plant (Xerces.org). This is a great plant for those infertile, hot, dry spots where little else grows. There are mixed reviews when it comes to the spreading habits of Old Field Goldenrod. Mine has barely spread at all, but it is not in its ideal location. Some sites say that it can spread aggressively, so just be aware of its potential to spread. I would be happy to hear how yours are growing. 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.
