Detailed Information

Flower: Flower shape: irregular

[photo of flowers]  Irregular blue-violet flower, occasionally pink or white, 1 inch across. The upper lip is divided into 2 erect lobes and the lower lip has 3 rounded lobes. At the base of the middle lobe are 2 pale yellow to white spots. A whorl of sepals about 1 inch long with 5 long teeth form a tube behind the flower. The flowers arise on longish stalks from the leaf axils. One plant may have many flowers.

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

[photo of leaves]  Leaves are 2 to 4 inches long, ½ to 1 inch wide, with fine widely spaced teeth, tapering to a point at the tip, the rounded leaf base clasping the stem. Leaves and the square stem are both hairless. Leaf attachment is opposite.

Notes:

This one is easy to ID, as there is nothing else like it in Minnesota, though a similar species with stalked leaves is native a bit farther east. Mimulus is one of the species that was formerly in the Scrophulariaceae (Figwort) family and is now in Phrymaceae (Lopseed). There are 2 varieties of M. ringens in North America; var. ringens found in Minnesota.

Another wild flower I've seen on my walks by the Mississippi River in Stearns County that I did not know the name of. Now I can name the photos I took of it last year.

Is this plant (monkey flower) only in purple? I have recently seen quite a few that look similar to this only they are yellow. Are they the same plant? I looked at your site under the yello flowers and didn't see anything that was as close as this one is. I found it in Jordan, MN. Believe it or not at the Water Treatment Plant because it is the ideal place to walk my very large, ambitious dog. many beautiful plants growing there though!

Yes, there is at least 1 species of yellow monkey flower that should be growing in various places around Minnesota, including the Twin Cities area: Mimulus glabratus. I haven't seen it myself, but I know it has to be here somewhere. A water treatment plant sounds like the perfect place for these moisture-loving plants to grow. :)

I found this on the side of a trail through my woods. I hadn't seen it before and brought it in to identify it from one of my books. I was unable to find it there, and found it here! Thank you for helping me identify another wildflower on my property.

I found this plant blooming today in a drainage ditch in my back yard that is always wet. I have been working this area into a wetland garden and I am always on the look out for natives that just show up like this one.

I found this today on our lake shore. We are finding a number of species we have never seen here before after flooding 2 years ago. July 2014

I brought one small plant that looks like this back from western Wisc. The flower looks like a pink and white orchid, no larger than an inch. Invasive: do not need much water, grow to four or so feet. Same plant?????

Karen, it's not likely an orchid (which come in a vast array of sizes, shapes and colors) but other than that your description matches many different plants. Did you try the advanced search and see if you spot it there? If not and you want more help post an image on our Facebook page and we'll take a look.

one of three "strangers" I recently found near a slough at the edge of woods on our property. Also found--woundwort, wild mint and blue vervain. Had never seen the first three before.

See "where to buy native seeds and plants" that is on almost every page at this site. If those vendors don't carry it, ask if they know one that does.
