Detailed Information

Flower: Flower shape: 4-petals Cluster type: raceme

[photo of flowers] Loose cluster of stalked flowers (raceme) more or less evenly spaced along the top of the stem, often with a few lateral racemes from the base of the cluster and/or the upper leaf axils. Flowers are 1/8 to ¼ inch across, have 2 white to pinkish petals each 1.6 to 2.9 mm long, notched to about half their length, with 2 green egg-shaped sepals about the same length that bend back away from the flower. In the center are 2 white stamens slightly longer than the petals. Beneath the flower is a hairy ovary. Flower and cluster stalks are sparsely covered in short hairs, at least some of which are gland-tipped.

Leaves and stem: Leaf attachment: opposite Leaf type: simple

[photo of leaves] Leaves are opposite with pairs at right angles to the pair below, 2 to 6 inches (5 to 16 cm) long and to 3+ inches (2.5 to 8.5 cm) wide, minutely toothed around the edges, narrowly to broadly egg-shaped to oblong, tapering to a pointed tip, on a stalk 1 to 2 inches long. Leaves become rather smaller towards the top of the plant. Stems are single, erect, mostly hairless below the flower clusters. Colonies can form from horizontal, underground stems (rhizomes).

Fruit: Fruit type: barbed Fruit type: capsule/pod

[photo of developing fruit] Fruit is a capsule 2.8 to 4.5 mm long and covered in hooked hairs that attach themselves to anything that passes by. When mature, the capsule is pear-shaped to nearly round, with several distinct ribs or grooves.


Enchanter's Nightshade, also known as Circaea lutetiana, spreads by both seed and rhizomes, often creating small colonies in woodlands across much of Minnesota. Beware walking through the woods in late summer when this has mature fruit or you may end up with tons of it stuck to your clothes, or in your pet's fur.

There are 2 recognized subspecies: subsp. canadensis is the North American species and subsp. quadrisulcata (C. quadrisulcata) its Eurasian counterpart. Closely related is Alpine Enchanter's Nightshade (Circaea alpina), a much smaller plant which has open flowers all clustered at the top of the raceme rather than along the stem, rarely gets more than 10 inches tall at maturity, has fruit lacking ribs/grooves, leaves are more coarsely toothed, and favors cool, moist woods and swampy places, often found on moss-covered rocks and logs. The two can hybridize, the hybrid (C. ×sterilis) having intermediate characteristics.

Bountiful in the area with delicate pink flowers.

I was just at my parents little spot up north in Ross Lake Township of Crow Wing County (by Aitkin), and I just successfully ID'ed these growing quite well among a host of ferns, grasses, maples, pines, and birch trees. They are just off of Stark Lake. They reminded me of bishop's cap at first. So lovely in the forest, it's amazing how many people miss noticing these small beauties.

In my shady side garden, among the monardas and dicentras. Like Carrie Anne, my first thought was of Mitella.

Abundant in shady areas of suburban yard which were allowed to naturalize after the land had been farmed and then managed as a lawn for many years.

Lots of the Alpine and C. lutetiana plants blooming in and around the large planted White pines in Sand Dunes SF on July 3, 2016.

Coming up under the edges of a spruce tree in my wildflower garden. Mostly shade, some afternoon sun. New Jersey Tea grows well right next to it.

I have found this plant on my property here near Ottertail, and the little seeds, i.e.-burs, love to hitchhike on my dog's fur. My dog sitter in Little Canada, MN, has a ton of these in his yard and the burs turn my dog green in late summer.

A small colony appeared this year in the same location where I cleared out some black nightshade last year, under a giant white pine, mostly shade.

This plant is abundant in my area. It is taking over the shades portion of my yard.

First time in 10 years I have seen them in the woods on my property.they are pretty.

If it's the same plant, my back wooded area is full of it. The flowers are easy to overlook, but the burrs are a nightmare.
