Once you recognize it, it is everywhere
I have one purpose here: to cause a single reader to discover a common plant growing right outside their back door, right under there noses, but never noticed. And certainly never named or known.
If a single one of you tells me “YES! After learning about this native plant and actively LOOKING for it, I have seen it. And it is everywhere!” I will consider my small efforts here to have been successful.
The plant is HORSEWEED. Conyza canadensis (formerly genus Erigeron—the fleabanes.)
- It has many common names
- It has tremendous reproductive potential
- It has become a serious herbicide-resistant pest in food crops, especially no-till
- It has spread from Canada to China and Europe, with which North America has shared a native-become-invasive
- Horseweed has been used as herb and medicine. Crush and sniff the leaves for a tarragon-like aroma.
- Its stems can be used to start a fire [I plan to see if I can make this work and will let you see the blisters on my hands afterwards.]
Below are images of the plant in its basal rosette form seen very early in the spring, followed by a couple of 8 foots specimens growing near the Generac here at the house. You will gain an appreciation for the ability of this plant to spread its dandelion-like floating seeds across distances.
And lastly, as testament to my late-onset laziness and knowledge that few readers click links provided, I bundled my unprocessed notes (mostly cut and pasted from the web) in a screenshot of related horseweed info in OneNote. You can search out anything that interests you from there.
And if you “discover” horseweed after reading this, please let me know, and I will consider the two cups of coffee it took me to create this post well worth the trips to the kitchen in the wee hours. — fred



You might be interested in seeing how horseweed “stems” can be used to hand-drill a fire. Go to 3:45 for the fire-starting part, though there is no fire, just the motions involved.
