  • Species Scientific Name Phacelia argentea
  • Federal Listing Status Species of Concern

Special needs

Silvery phacelia occurs on unstabilized or semi-stabilized sand dunes, bluffs, and at the bases of coastal headlands. It is found above the high tide line but generally below 65 feet in elevation.

Limiting factors

Habitat loss due to European beachgrass invasion and urban development is a key threat to this species. Off-highway vehicle use also adversely affects silvery phacelia.

Conservation actions

Continue efforts to control European beachgrass and manage off-highway vehicle use at occupied sites. Continue to monitor populations.
