Hi, Can anyone help me identify this plant? It thrives here in the Pacific Northwest - on shale, in gravel, in grass. The small yellow flowers look similar to Arnica, but the leaves are not opposite. I have taken four pictures to show the flower and leaves. The deer eat off the top and it just grows back with more flowers.
Thank you for the ID. I have been working at keeping this plant under control ever since we had our driveway done.
