The plant is endemic to chaparral habitats in Southern California.

Most of the populations are in a region from southern Monterey County to Los Angeles County, but there are a few isolated populations reported from Riverside County.[4]

Description

Baccharis plummerae is a bushy shrub producing many erect, slender stems approaching 2 metres (6.6 ft) in maximum height.[5][2]

The leaves are linear to oblong in shape and sometimes have fine teeth along the edges. They may be up to 4.5 centimetres (1.8 in) long.[2]

The shrub is dioecious, with male and female plants producing flower heads of different types. The head is enclosed in a layer of phyllaries which are glandular and sticky. The fruit is a ribbed achene with a pappus 7 millimetres (0.28 in) or 8 millimetres (0.31 in) long.[2]
