For Sean Hogan, owner of Portland’s Cistus Nursery, known for introducing xeric and Mediterranean-climate plants from around the world to the Northwest, said you need to become a weather detective to zone surf.

The specimen examined from four miles north of Jaumave was trapped in a xeric area in which the vegetation consisted of mesquite, high palmlike yuccas, and "lechugilla."
