Anemone canadensis

I also find this plant very invasive. It propagates at an alarming rate by rhizome and seeds at an alarming rate and will take control of a mixed perennial bed in less than 3 years.

But it is great for naturalization.

If you want to transplant them, do so in spring before flowering. The plants will become dormant and disappear, with foliage coming back in the fall and lots of flowers the next spring.

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.
