 The single remaining large population, in Edgewood County Park, is a relict of a more extensive colony damaged by off-road motor-vehicle use.There is an introduced population at Pulgas Ridge Open Space Preserve, and native fragments along the lower slopes above Crystal Springs Reservoir in a six-mile-long (10 km) fragmented strip that includes the Edgewood colony.This species is only known to grow on serpentine soils.
