I saw a couple plants for the first time (for me) ever on 9/3/10 in a ditch along the main path into the park, standing in water in the exact same spot as the marsh cinquefoil and broad-leaf arrowhead were earlier this year. On 9/4/10, I noticed that the little pothole just inside the 45th-and-Granada entrance is FULL of these! For the last several years this pothole has been dry by July but with all the rain this year it's now full of water. And Bidens cernua!

Found this plant by our lake. Such a pretty flower and interesting leaf. Don't know why I've never noticed it before. I just discovered this website. I find I am using it a lot. Thank you :0)

A number of these popped up along our lake shore this late summer and early fall. They are all nodding and drying up by 1st of October.

I love this website. Great information on wildflowers. Yesterday, I spent hours picking the burs from nodding marigold out on my jeans and sweatshirt after walking along the shore of our slough. The flowers were lovely earlier this fall, and I am delighted to now know the name of this plant.

I found these flowers in at least two locations near Wahkon. I'll have to collect samples to update the distribution map.

I love this website! Bought something from Amazon but I have a hard time finding anything on it and the pictures are not nearly as good. Found this in a wet roadside ditch.

Maplewood State Park on the spit of land that separates North and South Lida Lake.

These surround my pond just north of Long Lake in Medina. I believe your height specifications need to be revised, however. Mine grow up to 72 inches tall.

Thomas, if your plants are six feet tall it is more likely a different species.

These flowers bloom in swamp on our property. I have lived here since 1964. They bloom particularly when swamp is mostly dry like this summer.

Growing thick along shore of Prairie Lake in Crow-Hassan Park Preserve.

Growing along the edge of my pond.

Is the species epithet cernua or cernuus? I have seen it spelled both ways. However it is spelled the flowers are great nectar sources for a variety of syrphid flies.

Bidens cernuus might be from old taxonomy; it's not widely used. B. cernua is the accepted name.

Anyone in the Twin Cities metro area see these currently blooming? I'd like to send my dog through a patch of them to collect the seeds. I have a spot of perpetually wet soil in my yard that I would like to grow these on.

Scott, you must really hate your dog :-)

Pretty sure this is what is blooming in our slough. In the spring it's filled with water (this spring was wet enough that we had a couple of wood ducks), but it usually dries out by August. We have false sunflowers around the edge of our yard so at first glance I assumed that's what these were, and I haven't trudged out there to make sure, but the flowers seem smaller and the fact that beggarticks are commonly found on the banks of ponds in late summer or early fall makes me think this is probably what it is.

I found today (Sept. 16) what appear to be several of these plants growing in the stream run of a pond at The Millenium Gardens in Plymouth. They are 8 to maybe 12" tall and currently in full bloom. There were pollinators on the flowers. It appears that this species has not been noted for Hennepin county.

Mandy, the MN DNR's Biological Survey did record this species in Hennepin County, it just didn't get added to their MNTaxa distribution map. That seems odd, but sometimes happens.

This popped up in a newly wet area (that also exploded with cattails this year) Plant is 3-4 tall with many blooms. Very pretty, cheerful plant.

A pond on our property has receded this summer and there are MANY of these around the perimeter. Since the pond is in our horse pasture, I am wondering if this plant is toxic to horses. Thanks.

Wendy, this should be a common species in your area. You could ask your vet about it.

Rose Lake, Martin County, MN. Rose Lake has receded this year giving way to Bur Reed, Bulrush and Nodding Bur Marigold.

Along the shore line, on the beach.

We have a nice colony of Nodding Bur in one of our wetlands. What I thought was noteworthy was the large number of pollinators (seems to be heavy on bumblebees) that apparently love this plant. The flowers are just humming.

Large colony in pond that was dried up earlier this summer, but took on water over the last two weeks with the heavy rains.. located in Freeman park on path through the woods.

There are quite a few plants along the sandy, mucky edge of Rice Creek along the channel where it flows out of Baldwin Lake in the Rice Creek Chain of Lakes Park Preserve.

A large colony is in bloom in a dry pond in Battle Creek Park just west of Winthrop St. It is easily viewed from the front ski trails nestled near a wooded area. Lots of bees visiting. Fall prairie flowers are also in their September glory!

This appeared in the summer of 2021 at the shore of our little stormwater pond in Maple Grove, growing right at the margin or actually in the water. Pond is shallow.

I have a nice patch of these in an occasionally flooded portion of my yard. Such a nice, cheery look while they're blooming. Later, perhaps the persistence of the ripe seeds will discourage little boys from disturbing the area! From casual observations, I have the impression that year by year, their appearance varies - I assume due to variability of the water levels during germination season.
