Comment:

Rørslett (2012) first showed a botanical garden specimen of Sanguinaria canadensis in ultraviolet⁽¹⁾. Here is a wild example which has moderately UV-absorbing petals with UV-black reproductive parts.

Often found growing in shady woods, the Sanguinaria flower appears before the leaves are open in very early spring. The red plant sap is considered toxic. Morphology can be quite varied.
