Ceanothus pumilus
is a species of shrub in the buckthorn family Rhamnaceae known by the common names dwarf ceanothus and Siskiyou mat. It is native to the mountains of southern Oregon and northern California, where it grows in habitat such as coniferous forest and chaparral, often on serpentine soils. This is a low-lying to flat shrub taking the form of a mat or bramble up to about 2.5 meters wide. The tiny evergreen leaves are oppositely arranged, each just over a centimeter in maximum length. They are firm and ribbed, flat or cupped, hairless on top and generally hairy and paler in color on the undersides. The flower cluster is a small cluster of flowers in shades of blue, lavender, or white. The fruit is a horned capsule about half a centimeter long.
