Upland Boneset: A Rare Native Gem for Your Wildflower Garden
Looking for a native plant that’s both beautiful and beneficial to wildlife? Meet upland boneset (Eupatorium sessilifolium var. vaseyi), a charming perennial that deserves a spot in more gardens. This lesser-known variety of boneset brings late-season blooms and attracts a parade of pollinators when most other flowers are calling it quits for the year.
What Makes Upland Boneset Special
Upland boneset is a native forb—essentially a non-woody perennial that dies back to the ground each winter and returns stronger the following spring. Don’t let the scientific name intimidate you; this plant is actually quite approachable for home gardeners. You might also see it listed under its botanical synonyms, including Eupatorium vaseyi or Eupatorium album var. vaseyi, but they’re all the same delightful plant.
Where It Calls Home
This native beauty naturally grows throughout much of the eastern United States, spanning from Alabama up to Pennsylvania and from Delaware west to Kentucky. You’ll find it thriving in states like Virginia, North Carolina, South Carolina, Georgia, Tennessee, West Virginia, Maryland, and even in the District of Columbia.
A Word About Rarity
Here’s something important to know: upland boneset is considered rare in New Jersey, where it holds a status of Highlands Listed, S2. This means the plant has limited populations and is considered imperiled in that state. If you’re lucky enough to find this variety for sale, make sure you’re purchasing from reputable native plant nurseries that source their plants responsibly—never collect from wild populations.
Garden Appeal and Design Uses
Upland boneset shines in late summer and fall when it produces clusters of small, creamy-white flowers arranged in flat-topped displays called corymbs. These blooms create a delicate, almost lacy appearance that works beautifully in:
- Native wildflower gardens
- Meadow-style plantings
- Pollinator gardens
- Woodland edge areas
- Naturalized landscapes
The plant fits perfectly into informal garden designs where you want that wild look without the chaos. It’s especially valuable for extending your garden’s blooming season into fall.
Pollinator Magnet
One of upland boneset’s greatest gifts to your garden ecosystem is its ability to attract beneficial insects. Butterflies, native bees, and other pollinators flock to the nectar-rich flowers, making it an excellent choice for anyone wanting to support local wildlife. The timing of its blooms—late in the season—provides crucial food sources when many other flowers have finished blooming.
Growing Conditions and Care
Good news for busy gardeners: upland boneset is refreshingly low-maintenance once established. Here’s what it needs to thrive:
- Sunlight: Full sun to partial shade (though it blooms best with at least 6 hours of direct sunlight)
- Soil: Well-drained soils; it’s quite adaptable to different soil types
- Water: Drought tolerant once established, though it appreciates occasional watering during extended dry spells
- Hardiness: Hardy in USDA zones 5-9
Planting and Care Tips
Getting upland boneset established in your garden is straightforward:
- Plant in spring or fall when temperatures are mild
- Space plants about 18-24 inches apart to allow for spreading
- Water regularly the first year to help establish strong root systems
- Cut back spent flower heads if you want to prevent self-seeding, or leave them if you’d like the plant to naturalize
- In late fall or early spring, cut the entire plant back to about 6 inches above ground level
One delightful trait of upland boneset is its tendency to self-seed when happy. This means you might find new plants popping up in your garden, creating natural drifts over time.
Is Upland Boneset Right for Your Garden?
This native variety is perfect if you’re looking to:
- Add late-season interest to your garden
- Support native pollinators and wildlife
- Create low-maintenance plantings
- Grow something truly special and somewhat rare
- Embrace the natural beauty of native plants
The main consideration is availability—since this variety is less common than other bonesets, you might need to seek out specialty native plant nurseries. But for gardeners who appreciate the unique and want to grow something that truly belongs in their local ecosystem, upland boneset is absolutely worth the hunt.
Remember, when you choose native plants like upland boneset, you’re not just creating a beautiful garden—you’re helping preserve the natural heritage of your region and providing habitat for local wildlife. That’s gardening with purpose, and it doesn’t get much better than that.
