Eaton Canyon Natural Area Park lies at the base of the San Gabriel Mountains, at the mouth of Eaton Canyon, whose upper reaches start near Mt. Wilson. Eaton Canyon creek usually has year-round water, but becomes an intermittent stream near the Mt. Wilson Toll Road bridge. Eaton Canyon wash, which runs through the park, has water only part of the year. You can find an abundance of different plant species, because the area consists of five plant communities: Coastal Sage Scrub, Chaparral, Southern Oak Woodland, Riparian Woodland, and Alluvial Scrub, plus their ecotones at their edges, where the communities blend together.
Below is a partial list of the most common and naturally occurring plants found in the park and the area along the creek north of the park, as far at the Eaton Canyon waterfall.
Plants that have an asterisk (*) after their names are those that are not native to Eaton Canyon. They have been introduced, intentionally or accidently, from other parts of California or beyond. Some are considered to be invasive.
