I have no idea what type of flower this is that I noticed this afternoon for the first time near the Kennedy Library on the Cal Poly campus. I have never seen this species before. It comes in at least two varieties as evidenced here with an image of one flower from each plant which were growing near each other near the intersection of North Perimeter Road and University Drive.
I'm open to any counsel from my readers as to what this flower is called. Both photos by Kim Patrick Noyes (all rights reserved).
