Detailed Information

Flower: Flower shape: 6-petals Flower shape: 7+petals

[photo of flowers] 1 to 6 stalked flowers in a whorl at the top of the stem. Flowers are ½ to 1 inch across with 5 to 10 petal-like sepals that are rounded or notched at the tip. Surrounding the green center are numerous yellow-tipped stamens. Flower color is pink or white and sometimes double flowers develop.

Leaves: Leaf attachment: basal Leaf attachment: opposite Leaf attachment: whorl Leaf type: compound

[photo of stem leaves] Basal leaves are long stalked, twice compound with 3 groups of 3 leaflets. Leaflets are hairless, have 3 or more shallow rounded lobes or notches at the tip end, are about 1 inch long and have a stalk up to about 1 inch long. An opposite pair of once compound leaves is at the base of the flower stalks but often the leaf stalk (not the leaflet stalk) is absent so they appear as a whorl of about 6 stalked leaves surrounding the flowers. Stems are multiple from the base, hairless, erect, and unbranched.

Fruit: Fruit type: seed without plume

[photo of fruit] Fruits are oval, about ¼ inch long and are ribbed.

Notes:

The flowers of Rue Anemone, Wood Anemone and Canada Anemone are all similar and they may all be in bloom around the same time, but the leaves are distinctly different enough to avoid confusing them, and Wood Anemone and Canada Anemone both more consistently have 5-parted flowers. Canada Anemone is also a much taller plant and blooms into the summer.

I found a couple of clumps in my wooded backyard in Rochester. I thought it was a snow drop at first, but a friend directed me to this site after a posted my picture on Facebook.

There are large colonies of these in the woods across the road from our home in South St Paul. I also rescued some from a construction site a few years ago and transplanted them to my shady garden, where they've really taken off nicely. They're one of my favorite spring wildflowers.

Found a small patch on a sloped woodland in front of our house today. Finally, some color in the Springtime.
