No, No, No!! I planted this into my garden, and it was ever-so-lovely for a few years. Then I noticed that it had overwhelmed and killed several of my ferns. Then I tried to dig it up -- it's roots are worse than quack-grass and can go 8 inches deep, under tree roots, etc. I've not been able to erradicate it by carefully sifting the soil or any herbicide. Here's what my research showed: "[False lily-of-the-valley] is a major weed problem in cranberry bogs in western U.S.. It resists all means of control with registered herbicides and gradually smothers out the cranberry vines. Complete removal of all soil infected with false lily-of-the-valley or fumigation are the only two control methods currently available."

This is a native plant in the Pacific NW. Whenever I bring forest dirt in to my flower beds, I get some of these. They make a nice groundcover and are easy to pull from areas you don't want them.

A pretty plant in bloom, with spikes of white flowers rising above glossy, clean leaves. But it's invasive and care should be taken when incorporating it into beds where it may elbow out less vigorous plants.
