Invasive plants #864655

Asked April 15, 2024, 5:49 PM EDT

I do live in Portland. I am trying to Distinguish between Geum Urbanum versus Macrophyllum. I want to know if what we have (3.7 acre cohousing property in NE) is an invasive species or a Very successful native.

Hello. We have not found an expert available to identify the pictured plant. Perhaps you have more leaf or flower photos?Oregon Flora has this listing for our native Geum. It is vigorous and in moist conditions can dominate a landscape. Homeowners often remove or discourage it.
