EDRR Status: Ongoing monitoring
Description of specimen
I have studied the online descriptions and am quite certain that this is in fact sulphur cinquefoil. I can provide photos and a sample should you require them.
Thank you so much for reporting sulfur cinquefoil (Potentilla recta) and sharing your concern of additional spread! According to www.weedmapper.com, this species has not yet been reported from Jackson County. That means this is an "early detection" of this species and survey and rapid response in your area may be justified. It would be good to make the adjacent land owners aware so they can be on the look out of this species. Thanks again for your report. This is very useful!
It sounds like you are certain of your identification; however, because this species is so easy to confuse with the native cinquefoil (Potentialla gracillis), it would be useful if you could submit a photo so we can confirm the identification. The main difference between the native and the invasive cinquefoil is that the back side of the native leaves look white, while the invasive is more of a pale green. You can submit the photos by returning to your report (click on the link), and uploading. Let me know if you have any trouble (contact info below). Thanks again for your report!
Sincerely,
Tania
