|Crop field in Delaware County, Ohio|
It's all over central and western Ohio, but by looking at this map, you'd think it was a rarity. It's even showing up in my front yard as a weed! Why has this plant expanded so rapidly? Is it taking advantage of no-till agriculture? Is there something else to the story? I'm not sure, but I bet that it grows in every county in Ohio's corn belt plains, and on this map, it barely registers in a few Ohio counties.
Plants get around- they move, and they can do things that we never expect. And that's why I think they're incredibly cool. Look out Pennsylvania, butterweed may be headed towards you!
p.s. (I bet it's probably there already)
