Forget the strange and macabre name (we’ll tell you where it comes from in a minute). Bonesets are tremendous flowers—tall, majestic, and an important food source for pollinators at the end of the growing season. Like another tall native Joe Pye weed, boneset grows 4-6′ and opens up nectar-filled umbrellas of flowers at the end of summer into fall. They are stunning from afar, but be sure to get up close to appreciate dozens of pollinators zipping around. Scroll on for planting tips.
Is boneset a good choice for my yard?
Yes, if…
- You want a tall, dramatic flower that feeds pollinators when other blooms have faded.
- You have a moist garden spot—a place where water pools after rain or along a stream, pond, or rain-collecting area.
- You’re building a pollinator garden or want to support Monarch migration.
- You like plants that come back year after year with little care (perennials).
Why boneset matters
- Late-season lifeline: Provides nectar when other flowers have gone to seed.
- Time-saver: Low-maintenance, no fertilizer needed, thrives on rainfall alone.
And one more benefit to planting boneset… 🦋
Planting boneset helps dozens of iconic butterflies and moths, including:
New to native?
Before lawns and landscaping, native plants were here. They’ve fed birds, bees, and butterflies for thousands of years—and they’ll do the same in your yard. The best part? They’re easier to grow than you think.
Where it grows naturally
In the wild, boneset grows in wet meadow communities or places where sunlight and water meet. You’ll find it along streams, ditches, and pond edges surrounded by Joe Pye weed, swamp milkweed, and blue vervain.
In a yard, that looks like low spots, rain gardens, or areas that stay damp after rain. Planting boneset there recreates a slice of that natural community, and a late-summer haven for bees, butterflies, and migrating monarchs.
Where is boneset native?
Native to 37 US states, Washington, D.C., and 6 Canadian provinces (Manitoba, New Brunswick, Nova Scotia, Ontario, Prince Edward Island, Quebec)

How to grow boneset
There are a few things to note as you consider planting boneset in your yard:
- Make sure boneset gets consistent moisture. As mentioned, in nature, Boneset is found alongside waterways. Mimic this environment by putting them in areas alongside water or where water pools after rain.
- Give them space. Boneset will spread over the years and form a colony of plants. Plant them where they have space to spread out.
- They get tall—4-6’—as large as most adults. Put them in the back of pollinator gardens surrounded by medium and short-height flowers.
However, even if your garden experiences short periods of drought, established bonesets can survive. (The two-year-old boneset in my PA garden has received zero watering and is still in full bloom, even with several weeks of no rain.)
2-3 ft wide
Why is it called boneset?
Boneset’s unusual name comes from early beliefs that it could ease pain, especially in cases of “Breakbone Fever,” now known as Dengue Fever. Native Americans and early settlers used boneset in herbal remedies to reduce fevers and promote healing, believing it could even aid in mending broken bones.
However, if you’re thinking about using it as a remedy, be aware: the U.S. Forest Service warns that boneset can be emetic and laxative in large doses and may contain pyrrolizidine alkaloids, which are potentially harmful to the liver.
Do any other plants have weird names like this?
Yes! Many plants have common names that reflect their long-ago medicinal uses. Others include: rattlesnake master and Joe Pye weed. For native plants currently in medicine cabinets, visit our Beginner’s Guide to Coneflowers (aka Echinacea).
One last story about its Latin name
This next part of boneset’s story is worthy of a Hollywood movie.
Its Latin genus name, Eupatorium, honors Mithridates VI Eupator, a 1st-century BCE king known for his wars against the Roman Republic and expertise in herbal medicine. Mithridates is said to have regularly ingested small amounts of poison to help build immunity. When Latin botanical naming was introduced in the 1700s, Eupatorium was chosen as the genus name to link to this mythical story.
Where boneset shines in your yard
Boneset is a standout in rain gardens and damp areas, but it’s not limited to wet spots. Once established, it can also handle average garden soil, making it a versatile choice for many yards. Its tall height (4–6 feet) means it shines in the back of pollinator beds or naturalized plantings where it can tower gracefully over shorter companions. In late summer, its cloud-like clusters of white flowers glow in the garden and draw in a frenzy of bees, butterflies, and even migrating monarchs—making it both a pollinator lifeline and a dramatic garden centerpiece.
