This plant grows up to 35 cm (12 in) tall, with one simple stem bearing
evergreen, shiny, toothed leaves in opposite pairs or
whorls of 3-5 (and sometimes more) along the stem. Leaves have a slightly spiny
serrulate margin starting close to the base, and range from 1 ½ to 2 ½ inches long (or longer) with a typically oblanceolate shape. Flowers range from white to pink, produced in a small
umbel of 4–8 together. The filaments have a roundish expansion at the base, bearing hairs along the margin only. In comparison, the closely related
C. menziesii bears hairs on the
back of the filament's expansion as well. == Ecology ==
