Skeletonleaf Bur Ragweed: A Hardy Native with Unique Appeal
Meet skeletonleaf bur ragweed (Ambrosia tomentosa), a perennial native that might not win any beauty contests but certainly earns gold stars for resilience. This unassuming forb has been quietly thriving across America’s heartland for centuries, and there’s more to this silvery-leafed survivor than meets the eye.
What is Skeletonleaf Bur Ragweed?
Skeletonleaf bur ragweed is a native perennial forb – basically a non-woody plant that dies back to the ground each winter but returns faithfully each spring. True to its name, this plant sports deeply lobed, skeleton-like leaves covered in soft, silvery hairs that give it a distinctive fuzzy appearance. The small, greenish flowers aren’t particularly showy, but they serve an important ecological purpose.
You might also encounter this plant under several scientific synonyms, including Franseria tomentosa and Gaertneria tomentosa, depending on which botanical reference you’re consulting.
Where Does It Call Home?
This hardy native has claimed territory across a impressive swath of the United States, thriving in Arizona, Colorado, Idaho, Illinois, Iowa, Kansas, Missouri, Montana, Nebraska, New Mexico, North Dakota, South Dakota, Texas, Utah, Wisconsin, and Wyoming. That’s quite the geographic resume!

Planting and Care Tips
The beauty of skeletonleaf bur ragweed lies in its simplicity. Plant it in spring after the last frost, give it some initial water to get established, then largely leave it alone. This is definitely a plant it and forget it kind of native.
Since it’s wind-pollinated rather than insect-pollinated, don’t expect it to be a major pollinator magnet. However, it does provide habitat and food sources for various wildlife species as part of a broader native ecosystem.
Best Garden Applications
Skeletonleaf bur ragweed shines in:
- Native plant gardens and prairie restorations
- Xeriscapes and drought-tolerant landscapes
- Naturalized areas where low maintenance is key
- Wildlife habitat gardens

The Bottom Line

Just remember that beauty in the plant world comes in many forms – sometimes it’s about resilience, adaptability, and ecological value rather than flashy flowers.
If you’re drawn to plants with character and history rather than just curb appeal, skeletonleaf bur ragweed might just be your kind of native companion.
