Detailed Information

Flower: Flower shape: 7+petals Cluster type: panicle Cluster type: raceme

[photo of flowers] Raceme or panicle cluster of 10 to 20 yellow dandelion-like flowers on short hairy stalks at the top of the stem. Flowers are about ½ inch across with 40 to 90 yellow ray flowers (petals) with notched tips. The bracts behind the flower are densely covered in short glandular hairs.

Leaves and stem: Leaf attachment: alternate Leaf attachment: basal Leaf type: simple

[photo of leaves] Leaves are mostly basal, up to 12 inches long, 1½ inches wide, with a rounded or blunt point at the tip, tapering at the base, toothless, and densely covered in hairs up to an inch long. There are a few alternately attached leaves to about the midpoint of the main stem that are much smaller. The stem is densely covered with long stiff hairs, becoming more sparsely hairy near the flowers.

Fruit: Fruit type: seed with plume

[photo of fruit]  Dark seeds about ¼ inch long with a tuft of light brown hair to carry them off in the wind.


An uncommon species, Minnesota is the northwestern corner of its natural range. Hairy Hawkweed does not colonize so it isn't likely to be confused with one of the weedy hawkweeds that tend to form large mono-cultures. When present, it is typically found as single plants scattered in the area. The hairs on the leaves and stem are longer than other hawkweeds.

Hieracium longipilum- believe I have a sighting for Pine County. Stay tuned. Can't recall the gal I chatted with on the slender penstemon find, but thought I would let her know of my find. :)

M J, the natural range of this uncommon species doesn't extend to Beltrami County and, unless one of your neighbors planted it and some seed blew your way, it is highly unlikely it just appeared in your lawn. You most likely have one of the weedy/invasive hawkweeds instead. If you'd like confirmation on your ID post some images on the Minnesota Wildflowers Facebook page.
