Smooth Rock Cress - Sanguinaria canadensis (Poppy family - Papaveraceae; Poppy subfamily - Papaveroideae) This delicate flower is short lived and opens only in full sunshine. The underground root contains a reddish juice that accounts for its common and generic names (from Latin sanguinarius, meaning "bleeding").



 

The pale, lobed leaf embraces the stalk bearing the showy 8 to 10 petaled flower and does not fully expand until the flower has bloomed. 6 - 12 in. Rich woods. Native Americans used the juice as a dye for their basketwork.
