wood poppy and yellow poppy. Members of the Poppy Family are characterized by their production of latex, which in the case of Stylophyllum diphyllum is yellow. They will bloom for several months, re-seed in the fall, and the whole stand enlarges each year.
Flowers begin as small hairy buds,
and emerge quickly.
The flowers have 4 yellow petals, 2 sepals, and multiple yellow stamens.
They have a single large stigma.
The stigma is the part of the female organ or pistil that accepts the pollen during fertilization.
