Yellow ironweed (Verbesina alternifolia, formerly Actinomeris alternifolia) grows in clumps of upright, “winged” stems: hence the other common name, wingstem. They’re topped in late spring to early fall with bright yellow, daisy-form blooms that are popular with butterflies and beneficial insects.
Yellow ironweed generally grows 4 to 8 feet tall, but the long-lived plants can eventually reach to 10 feet or more. At this size, and because of their tendency to self-sow, they’re obviously best-suited to a very large-scale borders and meadow plantings. This U.S. native pairs perfectly with the purple-flowered ironweeds (Vernonia), pink Joe-Pye weeds (Eutrochium), and tall grasses, such as big bluestem (Andropogon gerardii) and Indian grass (Sorghastrum nutans).
