Tragopogon dubius flower, Wenaha River Trail, Blue Mountains, Oregon, USA.

Tragopogon dubius flower blooms on Wenaha River Trail, Blue Mountains, Umatilla National Forest, Oregon, USA. Tragopogon dubius (commonly known as Yellow Salsify, Western Salsify, Goatsbeard, or Wild Oysterplant) is native to southern and central Europe and western Asia. The seed head resembles that of a large dandelion. After introduction into North America, it spread widely (invasively) across the continental United States and most provinces of Canada. The flowers open early in the morning and often close up by late afternoon. Western Salsify (T. dubius) looks very similar to the commoner Meadow Salsify (T. pratensis) except the green bracts behind the yellow flower are longer and more noticeable. Although not closely related to Meadow Salsify or Common Salsify or Oyster Plant (T. porrifolius), the Western Salsify readily hybridizes with both, and in North America its hybrids have created the new alloploid hybrid species T. mirus and T. miscellus.
