Perennial herbs that live at high elevations often spring up from underground storage organs to quickly produce flowers after snowmelt and then fade within 5-6 weeks. Two of these snowline geophytes, Dicentra uniflora and Dicentra pauciflora (Papaveraceae) have been investigated in the Cascade Range of northeastern Butte County. Hear how these closely related "steer's head" plants have responded to drought, animals, fire and other disturbances to survive in gravels at high elevation, with insights from 16 years of field data and long-term herbarium records.
