Glade Mallow - Napaea dioica (Rare: A native special Concern plant in Wisconsin)
Glade Mallow is a relative of hibiscus and grows between 3'-6' tall.
Glade Mallow blooms early June through early August. The flowers are 1/3 to 3/4 inch across with 5 white oval petals.
Glade Mallow is dioecious; which means that the male and female flowers are on separate plants.
Female flowers have a cluster of curly, thread-like styles atop a white ovary. Male flowers have a cluster of stamens in the center, the stalks (filaments) fused into a column with the pale pinkish tips (anthers) in a ball at the tip.
Leaves are quite large, up to 18 inches in diameter, round in outline, palmately lobed into 5 to 9 segments. Lower leaves are long-stalked, with leaves becoming smaller and shorter-stalked as they ascend the stem.
Other names for Glade Mallow : English mallow.
