Goat's-beard / Tragopogon dubius

This is the dreaded Goat's-beard, a highly invasive, non-native plant that has spread (and keeps spreading, despite attempts to control it) in our natural areas in the city. Too bad, because both the beautiful flower and huge Dandelion-like seedhead are most attractive. Taken on June 18th, in the Boat Launch area of Fish Creek Park.
