Ceanothus oliganthus is a species of shrub in the buckthorn family Rhamnaceae known by the common name Hairy ceanothus[citation needed], or Hairy-leaf Ceanothus.[1]


The variety of this species known as jimbrush (var. sorediatus) is sometimes treated as a separate species.[2]

It is endemic to California, where it can be found in most[citation needed] of the coastal mountain ranges in dry habitat such as chaparral.

It is found in the Santa Monica Mountains of California.[1]

This is a large, erect shrub approaching 3 meters in maximum height.[citation needed]

Leaves and stems=[edit]

The stipules (small leaf-like structures on the stems at the base of the leaf stem, are thin and fall off early.[1]

The evergreen leaves are alternately arranged and may be up to 4 centimeters long.[citation needed] They are dark green on top, paler and hairy on the underside,[citation needed] and are edged with glandular teeth.[citation needed] Leaves have 3 main veins rising from the base.[1] Leaves have a toothed edge.[1] The leaf is covered with short, soft hairs on the top.

Branchlets are flexible, not stiff.[1]
