DistributionMountains only. First collected in 1933 on road to Mack's [sic, Max] Patch in Henderson [presumed Haywood or Madison] County; this mountain lies along the county line separating these two counties.

Native of the northwestern states and provinces (fide FNA); now found throughout.
AbundanceRare to uncommon.
HabitatRoadsides, pastures, barnyards, fields, waste areas, campground weed.
PhenologyFlowering and fruiting May-November.
IdentificationThis is a poster plant of a "weed". It is short, scruffy looking, lacks bright colors or showy flowers, and the leaves are dissected into uninteresting segments -- not to mention growing in highly disturbed places. The terminal head (1 per stem or branch) is dull yellow and lacks rays. The sole redeeming feature is the delicious odor of crushed heads -- just like pineapple!
