Celandine Poppy
Stylophorum diphyllum)

Celandine poppies grow best in rich moist soil or a woodlands.  The plants will go dormant in the summer if the soil dries out, but will bloom prolifically in spring and early summer.  They will naturalize readily if growing conditions are favorable.

When crushed, the plants release a yellow sap.  Early Americans used the plant as a source of yellow dye;  Europeans also used it as a tonic and a laxative.
