Solitary yellow dandelion-type flower at the end of a long, naked, waxy, hollow stalk. Flower heads are 1 to 2 inches across with 15 to 150 ray flowers (petals), not usually as full or dense in the compostition and more coarse in appearance than the dandelion. The bracts behind the flower are in 2 to 3 rows, typically hairless, green, often purple tinged and/or spotted; the outer bracts shorter and broader than the inner bracts.
Leaves and stem:
Leaves are ¼ to 1 inch wide, ½ to 10 inches long, green to blue-green, generally linear to narrowly lance-like with a pointed tip, typically toothless but sometimes irregularly toothed or with a few shallow lobes, erect or prostrate. The plant is typically hairless throughout but may be sparsely hairy on the leaves or flowering stalk.
Notes:A native of Minnesota's western prairie meadows, False Dandelion can be frequent in relatively intact, diverse native habitats but it does not easily invade disturbed sites, so will not be commonly found across today's highly disturbed agricultural lands and roadsides. The USDA Plants database lists 6 varieties of this species but Flora of North America, our definitive reference, lists most as separate species and only 2 recognized varieties: A. glauca var. glauca, which is the Minnesota species, and var. dasycephala. All of A. glauca found in the US are primarily western species.
