Detailed Information
Flower:
1 to 6 orange to yellow-orange dandelion type flower heads emerge from the upper leaf axil, each flower on a long stalk, though rarely are more than 2 blooming at the same time. The stalk may be smooth or covered in glanduar hairs, especially near the base of the flower. Flowers have 25 to 60 rays (petals), orange stamens, and long narrow bracts.
Leaves and stem:
Leaves are mostly basal, to 10 inches long and 2 inches wide, hairless, narrower at the base and wider towards the tip (obovate) with pointed or rounded tips and “winged” leaf stalks. Leaf edges may be toothless, sparsely gentle toothed or somewhat lobed.
1 or 2 smaller, toothless, more lance shaped leaves clasp the stem about midway up the plant. Where the flower stalks emerge from the stem are 1 or 2 small clasping leaves. The stems exude a milky latex when wounded.
Notes:
Two-flowered Cynthia is one of my favorite composites (another name for the aster family) of what I call “the dandelion class”. Its clear mellow orange tinge instantly separates it visually from the rest of the crowd, and the 1 or 2 clasping leaves where the flower stalks emerge at the top of the plant further distinguish it. More than many other species this one clearly seems to track closely within specific biomes—deciduous forest and aspen parkland.Native Plant Nurseries, Restoration and Landscaping Services ↓

I believe I saw a bunch of these along the edge of Loring Pond in Loring Park. Does it make sense that they would be there? I think I've identified them correctly, but I'm not 100% sure.

I've seen clumps of bright orange flowers along the road between Orrock and Zimmerman MN and in a few places along north 169 They're about ten inches tall with a number of blooms. Anyone know what they are??

Carole, likely orange hawkweed. A very invasive pest plant. :-(

Is there a way to control these plants? They are taking over our yard. Thank you.

Marc, if you look at the distribution map you'll notice Krigia isn't known to be in the northeastern part of Minnesota. I suspect what you have taking over your yard is one of the invasive hawkweeds that are widespread in your area. Try some dandelion spray.
