5 Arisaema triphyllum Jack-in-the-Pulpit Seeds Native Woodland Shade Garden

Arisaema triphyllum, commonly called Jack-in-the-Pulpit, is a native woodland perennial prized for its distinctive spring bloom. Each plant produces a hooded spathe that curls over a spadix, creating the signature pulpit shape that gives this species its common name. It is a favorite among shade gardeners, native plant enthusiasts, and woodland landscape designers.

The unique flower structure adds curiosity and vertical interest to shaded borders, woodland gardens, and naturalized areas. After blooming, clusters of red berries can appear in late summer, and the foliage dies back as the plant enters dormancy. It grows best in consistently moist, humus-rich soil and pairs well with ferns, trilliums, and other woodland plants.
