Scientific name: Ranunculus micranthus
It’s native and a prolific spreader. The deer occasionally eat it. I’ve been using it as stringy tall-ish ground cover. It only grows to about 16″ tall.
Lately, I’ve been looking up the benefits of different plants, and I’ll need to get back to you on my observations for this one. So far, I can’t find anything about who this plant might benefit. If you know something about that, please comment below!
