Description:

Jack-in-the-Pulpit is one of New Jersey’s most uniquely structured plants and deserves a closer look! “Jack” is a spadix, or erect spike, hidden inside a “pulpit”, a sheath-like spathe that folds overtop the spadix. The flower structure exists in various combinations of green, purple and white stripes. The plant is hermaphroditic, producing only male flowers when young and forming both male and female flowers as they age. The flowers bloom in April and May, and mature female flowers will produce a conspicuous cluster of bright red berries by late-summer. Two large leaves divided into 3 leaflets tower above the flower. This shade-loving woodland plant requires moist, organically rich, loamy soil. This plant is relatively easy to grow in the right conditions and makes an attractive addition to shady native woodland gardens.

Wildlife Benefits: The flower is pollinated by small flies and the berries offer food for birds.
