Scientific Name

Eriogonum crocatum Davidson

Family

Polygonaceae

General

CI

     This plant, listed as "rare" by the State of California, is thriving at CSUCI. It grows from shear rock faces on both north and south facing slopes of hills.  It is observed flowering as early as February.

Post-Fire Observations    

      The above ground portion of many individuals of this species was consumed by the Springs Fire.  By July, living shoots were emerging from the bases if many of these damaged plants.  Additionally, many plants survived relatively unscathed living on rock faces where there was little fuel for the fire.  Some of these plants were flowering within days of the fire.
