Boneset

Highlights

Let’s put aside the strange and macabre name for a moment. 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 the intricate structures of their hundreds of tiny flowers. You can also hear them: listen for dozens of pollinators zipping around as you get close. Scroll on for planting tips.

Boneset is a native flower that has grown in North America for thousands of years. Its strange name comes from early beliefs that tea made from the plant could help ease pain. Thankfully, medicine has vastly improved. Today, we can enjoy these plants for their end-of-season blooms and leave the pain relief to medical professionals. In this article, we’ll discuss its name, share planting tips, and include some pairing suggestions.

Let’s dig in with the obvious question:

Why is it called Boneset?

Bonset’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 help mend 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.

Many plant common names come from perceived medicinal values

Common names for plants are names given by earlier generations. Quite a few North American native plants have common names that reflect their long ago medicinal uses. Imagine being an early European settler in the lush landscape of North America, relying on Native American knowledge to identify plants for food and medicine. You can see why some plant names were chosen to help aid survival. Other native plants named for their perceived healing powers include:

One last story about its Latin name

There’s another layer to Boneset’s story, 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. (There are about 60 plants in the Eupatorium genus, including another North American native: Joe Pye Weed.)

Now that we know the story about its names, let’s get to know the flower.

What are the benefits of planting native Boneset?

Bonesets, like native asters and goldenrods, are important native flowers because they bloom at the end of summer and into the fall when many other flowers have gone to seed.

Their flowers are crucial food for pollinators, including Monarch butterflies migrating back to Mexico. Planting Boneset ensures that bees, butterflies, and other pollinators have food before migration or hibernation.

Other benefits of planting native Boneset include:

  • Boneset thrives in a wide range of light: from shade to sun.
  • Late summer/fall flower-ers: at the end of the growing season, they cover themselves in flowers.
  • Low maintenance: no fertilizer or special needs are required for native Boneset to thrive.
  • Perennials: they will come back year after year. Once you plant them and they are happily established, you can enjoy them in your yard for years.
  • Time savers: native Boneset saves time and money compared to lawncare. Once native Bonesets are established, all they need is rain to thrive.

Does it remind you of another plant? There are a few native flowers in the same genus or that have similar flower shapes. Here are some similar natives:

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. 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 human 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.)
