Ethnobotanical Uses and Other Facts

Material Uses: Native peoples made baskets, hats and capes with the leaves. They were especially used for fine overlapping, trimming, and ornamentation. Leaves were a valuable trade item.
Landscape Uses: Does not flower every year.
Ecological Importance: Dominates the forest under story in many Cascade sub-alpine forests; wildfire triggers flowering.

Name Info: Xerophyllum means dry leaves, tenax means tough for the usefulness of the leaves in clothes and basket making.
