The large-flowered rush lily occurs in bogs, moist, open meadows, seeps, and wetland areas, generally at elevations of 1150-2300 feet. This species is often associated with overlying serpentine or peridotite soils. It is commonly found in open areas, with gentle slope.
Limiting factors
This species is severely impacted by cattle grazing. Mining, water diversion from bogs, off-road vehicle use, and land development are additional threats.
Data gaps
Conduct germination studies. Develop propagation and transplanting protocols.
Conservation actions
Maintain California pitcher-plant bogs, which provide habitat for many rare species. Minimize water withdrawals from bog sites. Carefully manage or eliminate grazing at sites where this species occurs. Collect/store seeds, including seeds from both white and purple flowers.
