Description of specimen

I work at Mary's Woods in Lake Oswego and a resident reported what they thought was something called Bermuda Buttercup growing in a natural area between our campus and Old River Road. There is a stairway that goes from our campus down to that road and the resident said she saw it near there.

We also have copious amounts of ivy growing the in the natural areas around our campus.

Is there a program that will assist us in removing these?


I checked the reported location out on 2/24/2020. I did not find Bermuda buttercup (Oxalis pes-caprae) or any other Oxalis species. However, there were several patches of Lesser celandine (Ranunculus ficaria) in the described location.
