Other names and notes
(Yellow Salsify, Western Goatsbeard) Plants of the genus Tragopogon are commonly called "Goatsbeards" while the different species have attached various common names. Goatsbeards are a close relation to the Hawkweeds. The plant is an erect biennial reaching to 3 feet in height. The flower head forms singly on a long stalk. It is about 1 1/2" wide and composed of pale yellow ray flowers, the outer ones much longer than the inner, and with small teeth at the tip. Anthers are black. The bracts, which number up to 13, are longer that the rays. The leaves are alternate, clasping and grass-like with straight pointed tips. Like T. pratensis, the Yellow Goatsbeard, the flower opens early and is frequently closed by early afternoon. This plant differs from T. pratensis where the leaves are backward curving and the flower bracts, while visible beyond the rays, are much shorter. "Goatsbeard" refers to the fuzzy seed head. The feathery down on each seed is on a long stalk and interlaced forming a tall narrow cup-like structure. This structure is easily taken up by the wind. Frequently seen on roadsides and other untended patches of ground.

Notes: This plant is a European import and is now found throughout all of Canada and the United States except for four southern states. In Minnesota it has been found in all but a small number of widely scattered counties. Martha Crone did not note it's presence in her 1951 Garden Census, nor was it listed on the 1986 census but was present in 2009. See T. pratensis, the Yellow Goatsbeard for more information on Goatsbeards and an example of the seedhead.
