Blochman's Erigeron
Erigeron blochmaniae

About Blochman's Erigeron (Erigeron blochmaniae) Erigeron blochmaniae is a species of flowering plant in the daisy family known by the common names Blochman's erigeron and Blochman's leafy daisy. This wildflower is endemic to California, where it is limited to the coastline of San Luis Obispo and northern Santa Barbara Counties. It lives in sand dunes and coastal hillsides, habitat which is currently declining as it is claimed for development. This is a perennial daisy growing from a stout woody caudex or rhizome and reaching heights of 40 to 80 centimeters. Its stem is lined with evenly spaced narrow straight leaves, each one to three centimeters long. Atop each hairy stem is an flower cluster, with flower heads each just over a centimeter wide bearing light blue or lavender to white ray florets and a center of golden yellow or greenish disc florets.
