Discussion

Tragopogon porrifolius is occasionally cultivated in Europe and naturalized across much of North America. It grows typically in sites drier than those of T. pratensis and in sites shadier and/or moister than those of T. dubius. As currently circumscribed, it may not be monophyletic, and nomenclatural changes for the populations here may be required. In North America, T. porrifolius hybridizes with both T. dubius and T. pratensis (= T. ×neohybridus Farwell, described from North America, and T. ×mirabilis Rouy, described from Europe).
