Erigeron supplex is a rare species of flowering plant in the family Asteraceae known by the common names supple daisy or supple fleabane.[2][3] It grows along the coastline and in the Coast Ranges in California, north of San Francisco Bay. It probably remains only in Sonoma and Marin Counties. There is a report of it growing well inland in Shasta County, but this is from a farm and probably a cultivated specimen.[3]

It is surrounded at the base by oval-shaped leaves several centimeters long.

The fruit is an achene with a pappus of bristles.[2]
