Discussion

Of conservation concern.

Variety giganteum occurs naturally only on Santa Catalina Island, Los Angeles County. Mainland introductions occur from Santa Clara County to Los Angeles County; the variety has also been introduced onto Santa Cruz Island, where it threatens the genetic purity of E. arborescens. Garden hybrids between </i>var.<i> giganteum and E. arborescens have been named E. ×blissianum H. Mason.
