The Canadians are invading!

Meadow anemoneThis little beauty, Canadian anemone, showed her face yesterday for the first time in this garden. I am really in love with the pure creamy colour of her petals (technically, sepals) and could hardly wait to see her again. The picture, unfortunately, does not do her justice.

Yet meadow anemone aka Canada anemone, a native North American plant, is said to be invasive. I find that label a little excessive, seeing as it's on the endangered list in three states. It does indeed spread by rhizomes, but it takes a few years to get established and probably would not reach pest status unless it had ideal conditions.

Annemone canadensisI have always found that the first year I transplant this into my garden, it struggles mightily. This was as good as it got last year. Sometimes it dies back altogether. But the next year it comes back a little healthier and by the third or fourth it starts to spread somewhat. Of course, I have been growing it in rather heavy soil, which may be slowing it down somewhat.

Anemone canadensis is a woodland plant, despite the name "Meadow anemone" and does best in damp, humusy soil with partial or dappled shade. I have seen it carpeting several square meters in a natural setting, but it definitely hadn't taken over the whole woods. If you've grown this and consider it wannabe goutweed, please let me know. That hasn't been my experience.

Janet you may regret that little Canadian anemone. She will take over everything and you will be pulling her out constantly. I started with one little flower and the front yard is full of them now. I keep pulling and pulling and they keep coming back! I have tried to dig out the roots, but they are like spider webs.......

Olivia, you may be right. I've been keeping my eyes open and I have seen beds where it pops up in the middle of other plants. I've also seen some beautiful stands that seem to be well-contained. Probably not a plant for people who like everything to stay within bounds. I haven't made up my mind yet. For now, she's staying.
