They crouched at the toe of a north-facing cliff, all hearts and flowers in a mass of pink. It flew by so fast I was unable to look closely, so I parked and hiked back to the rock face. Fine land slide material had built up over many years in one spot, just inches at the toe. In this well-drained, relatively infertile mineral soil grew the Pacific bleeding heart (Dicentra formosa). It was my first view of the plants in habitat, a very curious place for an understory perennial to grow.
