Logfia filaginoides (formerly Filago californica),[1] also called herba impia or cottonrose, is a small annual plant in the family Asteraceae, found in the Southwestern United States.[2]
It grows throughout Southern California to Texas and Mexico.[2] In the Mojave Desert, it grows in creosote bush scrub and Joshua tree woodlands.[2]
It is a hairy, erect, annual plant growing between 2" and 12" tall.[2]
Its 1/2- to 3/4-inch-long leaves are attached to the stems without a little stem (petiole) at the bottom of the leaf (sessile).[2]
The 1/8-inch flower heads are surrounded by upper leaves of about the same length as the head.[2] Each head has tiny reddish-purple disk flowers with the outer 8–10 being all female.[2]
Fruits are tiny, flattened achenes with a ring of pappus bristles, falling off as a unit.[2]
