Wingstem (Verbesina alternifolia)
Verbesina alternifolia (Wingstem) is a tall, low-maintenance perennial offering bright yellow blooms late in the season.
Complete Plant Information
Overview
Wingstem, scientifically known as Verbesina alternifolia, is a commanding, tall-growing herbaceous perennial highly valued for its late-season floral display. This native plant naturally occupies woodland margins and damp meadows across Eastern North America, providing essential nectar when many other summer bloomers fade. Its dramatic height, often reaching 6 to 8 feet, makes it a structural element in naturalized settings.
The defining characteristic of Verbesina alternifolia is the distinctive webbing of leaf tissue running down the stem—the “wingstem”—which gives the plant its common name. While it is sometimes perceived as weedy, its profuse, bright yellow, daisy-like flowers are showy and attract a variety of late-season pollinators. Gardeners seeking vertical interest and low-effort native color will find wingstem to be a robust and rewarding choice.
This plant establishes itself easily, thriving in average to rich soils, and requires minimal intervention once established. Its ability to tolerate both full sun and partial shade, coupled with low maintenance needs, solidifies its role in sustainable landscape design, especially wildflower meadows.

How to Grow
Verbesina alternifolia is remarkably adaptable, making propagation straightforward for most gardeners. It is easily grown from seed, offering a simple path to establish large drifts of wingstem. Plant initiates prefer average, medium, well-drained soils. For the best growth, site plants where they receive full sun, although they perform well in part shade conditions.
Care requirements for established wingstem are minimal. While it thrives in consistently moist, organically rich soils—mimicking its native stream-side habitat—it possesses good drought tolerance once it has matured. Avoid overly rich supplemental fertilizers, as this can lead to weak, floppy growth in such a tall plant. Moderate watering during extended dry spells is usually all that is required.
Maintenance is generally low. In late fall or early spring, you can cut back the stiff, hairy stems after the seeds have been dispersed by birds. The seeds themselves are attractive to wildlife, so delaying cleanup until early spring is often beneficial for local fauna.
Landscape Uses
Due to its substantial height and somewhat informal habit, Verbesina alternifolia is not recommended for formal front borders where it might overwhelm smaller specimens. Instead, its suggested use is to naturalize generously in native plant gardens or expansive wildflower meadows. It creates a stunning, sunny backdrop in cottage gardens during the late summer and fall.
When integrating wingstem into your landscape, consider pairing it with sturdier, shorter perennials that can handle the transition from average to moist soil conditions, such as Asters or tall native grasses. Its purpose is to blend structure and color seamlessly into a less manicured area. Because it is native, it supports local ecology effectively when naturalized.
Gardeners seeking this particular native perennial may need to source it from specialty nurseries focusing on native plants, as it is not always readily available in standard commercial centers. Plan to give this plant ample space, allowing its 2 to 6-foot spread to develop naturally without crowding.

Noteworthy Characteristics
Verbesina alternifolia commonly called wingstem or yellow ironweed is a tall, weedy, clump-forming perennial that is native to woodland areas in eastern and central North America. Bright yellow, daisy-like flowers bloom from August to October atop upright, stiff, hairy, winged stems growing 4-8’ tall. The namesake feature is the leaf tissue extending beyond the leaf base and down the stems of the plant, hence the common name of wingstem.
Tolerances
No specific tolerances listed.
Potential Problems
Wingstem exhibits excellent resilience, rarely suffering from serious insect infestations or prevalent disease issues in the garden setting. This robust nature contributes significantly to its low maintenance rating. Should localized issues arise, ensuring good air circulation and avoiding overly wet, poorly drained soil will help prevent fungal concerns, although the plant generally handles rich, moist conditions well.
Frequently Asked Questions
What hardiness zones is Wingstem suitable for?
Verbesina alternifolia is hardy across USDA Zones 4 through 8, providing reliable perennial interest across a wide geographic range in Eastern North America.
How large does Wingstem grow?
When mature, this herbaceous perennial typically achieves a height between 4 and 8 feet, with a spread that can range from 2 to 6 feet wide.
When does Wingstem bloom?
You can expect vibrant yellow flowers on Verbesina alternifolia to appear late in the growing season, generally blooming reliably from August through October.
What sun exposure does Wingstem need?
Wingstem performs best when situated in full sun but tolerates conditions as generous as part shade, making it versatile for various garden pockets.
Conclusion
The tall stature, late-season yellow blooms, and exceptional low-maintenance profile make Verbesina alternifolia an indispensable component for naturalistic gardens. This native Wingstem brings structure and vital late nectar sources to the landscape. Before planting, confirm that your site falls within USDA Hardiness Zones 4-8 and that you can provide a medium water supply to ensure a successful establishment.
Companion Planting
Selecting appropriate companions helps manage the strong vertical presence of Wingstem. Since it prefers rich, consistently moist soil and performs well near streams or in meadows, look for other moisture-tolerant natives that bloom concurrently or slightly earlier. Tall Sedges (Carex) or native cardinal flowers (Lobelia cardinalis) are excellent partners, as they share similar moisture requirements and create layered texture below the 8-foot reach of Verbesina alternifolia. Allow space, as clump-forming plants need room to spread, keeping in mind the 2-6 foot spread estimate for this beautiful perennial.
Wildlife Benefits
One of the most significant advantages of incorporating Verbesina alternifolia into your planting plan involves its positive impact on local wildlife. As a late-season bloomer extending into October, the nectar held within its numerous golden flower heads provides critical energy resources for migrating butterflies and late-season bee populations. Furthermore, birds are highly attracted to the seeds produced by the spent flower heads, offering natural winter feeding opportunities. Planting wingstem is a direct way to support biodiversity in your yard.
