This plant is native to my state of Indiana. It is said to repel wildlife. http://www.louisvilleky.gov/NR/rdonlyres/034D7B52-DA05-4FB1-...
I'm trying to plant a wildlife-friendly garden, so that's not a positive for me. However, it is great in a tough spot where you need something with vigor. Perfect for roadside gardens that get a lot of abuse (runoff, salt and sand) and in areas that need an aggressive plant to compete with a non-native/invasive species. The foliage looks good throughout the season and grows quickly to become a good ground cover. Does well in full sun and part shade. The flowers are white and pollinators love them

I had planned on leaving a Neutral rating but changed my mind after reading the others. It self-sows freely and doesn't seem limited by lack of sun or water. I do actually like this plant and had planned to keep it, but it has become a thug even in my woodland garden.

I discovered this plant growing wild on our property a number of years ago and transplanted a few to my mixed perennial border; although I have to agree with the comments about it being invasive and rapidly trying to take over, I've found that it's really quite easy to go through the flower bed in the spring and pull out whatever is growing where I don't want it and that pretty much takes care of it until the next spring. What I leave nicely fills in the bare spots between other plants as a ground cover. I would definitely recommend this plant, with the caveat that it might be difficult to ever completely get rid of it.

This plant is very lovely during early summer as it will send masses of flowers to the skies. But it is also very rapid spreading for a native species. I'm already surprised that this species is not planted more often because it is tough and I also never see it grow in a roadside environment. It will grow well both sun and woodland shade but for some reason it look very different in sun and shade. It grows faster in sun and bloom like crazy. In shade it will develop more leaves than usual but rarely blooms, usually tiny flowers but will spread by rhizomes anyway but more sparsely patches at first.

The key to enjoying this charming little thug is to place it where it's permitted to spread within a confined area. I have a strip of land between our patio and the pavement where I've planted viburnum opulus for privacy, and used the anemone canadensis as a ground cover. It's lovely!

As charming as it is, this plant is a thug in my garden. It spreads by seed and underground runners and it is very difficult to erradicate. If just a minute piece of the root is left in the soil, another will sprout up.The roots are brittle and break when you try to pull them.
The only reason this rating is neutral is because it is a pretty plant, and maybe it would be nice in the appropriate setting.

A pretty flower but this plant can be invasive to say the least. It would be a fine addition to a wildflower garden but I would not advise planting it in a mixed border.
