About Woolly Yerba Santa (Eriodictyon tomentosum) Eriodictyon tomentosum is a species of flowering plant in the waterleaf family known by the common name woolly yerba santa. This shrub is endemic to California, where it grows on the chaparral slopes of the central coast ranges. It reaches maximum heights anywhere from one to three meters. Its twigs and foliage are covered in a dense coat of white woolly hairs, giving the bush a silvery look. The leaves are oval and up to ten centimeters long and five wide, and they may have small teeth along the edges. The bush flowers in dense fuzzy bunches of very light lavender hairy blossoms, each a few millimeters long. The fruit is a tiny capsule less than three millimeters wide, containing about 10 minute seeds.
