A woodland wildflower with distinctive striped spathes enclosing a dark spadix that resembles a preacher in a pulpit. The plant produces attractive red berries in fall and is valued for its unique spring flowers and ornamental foliage.

Why grow it

Jack-in-the-Pulpit offers a distinctive architectural presence in shaded woodland gardens where many spring ephemerals blur together visually. Unlike related arums, its bold striped spathe and contrasting dark spadix provide clear ornamental interest in early spring, while the later berry display extends seasonal appeal into fall. It naturalizes reliably in moist, humus-rich soil under deciduous trees, making it a low-maintenance choice for native plant landscapes in eastern North America.

Watch out for

The plant's corm can take several years to reach flowering size from seed, so gardeners seeking immediate spring color should source larger nursery plants. Foliage emerges early and may be damaged by late frosts in marginal hardiness zones, though the plant typically recovers. Dormancy is complete by mid-summer, so companion plantings should account for this gap in ground coverage.
