Lamprocapnos spectabilis is a species of flowering plant in the poppy family Papaveraceae, native to Siberia, northern China, Korea and Japan. It is the sole species in the monotypic genus Lamprocapnos.
It is no wonder how the old-fashioned bleeding heart (Lamprocapnos spectabilis) got its name. The pillow-like flower is heart-shaped with a single dangling pendulous drop. Bleeding hearts are shade-loving woodland plants that bloom in the cool of spring. Although they stay in bloom for several weeks, the plants often become ephemeral, disappearing for the rest of the summer, if exposed to too much sun or heat. The roots are still alive and it will regrow in the fall or the following spring. The fringed-leaf varieties will repeat bloom throughout the summer.
