Solidago sciaphila, commonly known as Shadowy Goldenrod, is a perennial herb that is endemic to the Upper Midwest of the United States. It is specifically found on the bluffs along the Mississippi River in southern Minnesota, the driftless areas of southwestern Wisconsin, northern Iowa, and Illinois. This species thrives on dry cliffs and steep slopes with dolomite and sandstone bedrock, where it is part of a unique cliff ecosystem that supports specialized flora and fauna. Shadowy Goldenrod typically blooms from late August to late September, featuring plumes of tiny, bright yellow flowers that are highly attractive to pollinators such as bees and butterflies.

Shadowy Goldenrod is valued for its late-season blooms, which provide color and interest in the garden when many other plants have finished flowering. It is suitable for naturalistic plantings, rock gardens, and restoration projects, particularly in areas that mimic its native cliff habitats. In cultivation, it requires well-drained soils, preferably similar to the rocky substrates of its native environment, and it does best in full sun to part shade. While it is not commonly available in the nursery trade, its conservation status as a Special Concern species in Wisconsin and Minnesota and threatened in Illinois highlights the importance of preserving its natural habitats and considering its ecological role when planting. Gardeners should be aware that it may be susceptible to powdery mildew in humid conditions and should provide good air circulation to mitigate this risk.CC BY-SA 4.0
