COMMENTS

Over 100 species of Eriogonum are found in the Southwest.

In late summer and early fall, these plants turn red and are commonly seen on disturbed soils such as roadsides.

The desert trumpet’s distinctive inflated stalk was dried by Indians to use as pipe stems.

Also an important food for bighorn sheep, and a species of wasp deposits eggs in the inflated stem.
