Would be greatful if someone can identify this plant.....very invasive, yellow flowers in the summer and spread through the roots. When pulled, the sap leaves an orange stain on your hands!! I live in Colstream, British Columbia. Purchased our acreage a year ago and I have this plant rapidly spreading on one side of my yard. Want to control or get rid because very hard to control.
Welcome to the forums Pdarlington. Looks like Stylophorum diphyllum http://en.wikipedia.org/wiki/Stylophorum_diphyllum
Leaves and flowers are not quite the same...thank you for your response! I may have to wait until it flowers to identify!
