You’ll find this woodland gem naturally occurring from the Maritime provinces of Canada down through much of the eastern United States. Its range includes New Brunswick, Nova Scotia, Prince Edward Island, Quebec, and extends south through states like Connecticut, Maine, Massachusetts, New York, Pennsylvania, Virginia, North Carolina, and many others in between.

A Word of Caution: Rarity Considerations

Before you rush to plant Jack in the pulpit, there’s something important to know. In New Jersey, this northern variety has a rarity status of Highlands Listed, S2, indicating it’s considered quite rare in that region. This means if you’re interested in growing this plant, it’s crucial to source it responsibly from reputable native plant nurseries rather than collecting from wild populations.

Why Consider Jack in the Pulpit for Your Garden

Despite the need for careful sourcing, there are compelling reasons to include this native plant in your landscape:

  • It’s perfectly adapted to North American growing conditions
  • Supports local ecosystems and native wildlife
  • Adds unique architectural interest to shade gardens
  • Low maintenance once established
  • Fascinating flower structure that’s a conversation starter

Garden Design and Landscaping Role

Jack in the pulpit shines in woodland gardens, shade borders, and naturalized areas. It’s particularly well-suited for gardens that aim to recreate the feeling of a native forest understory. The plant works beautifully alongside other native woodland species and can help create authentic regional plant communities in your landscape.

Growing Conditions and Care

While specific growing information for Arisaema triphyllum stewardsonii is limited, plants in this group typically prefer conditions that mimic their native woodland habitat. They generally thrive in partial to full shade with consistently moist, well-draining soil rich in organic matter. These plants have evolved to grow in the dappled light and rich, leafy soil of deciduous forests.

The Bottom Line

Jack in the pulpit offers gardeners a chance to grow a truly unique native plant that connects your landscape to the broader ecosystem. However, due to its rarity status in some areas, responsible sourcing is essential. If you can find nursery-propagated plants from reputable sources, this woodland gem can be a wonderful addition to shade gardens and naturalized areas. Just remember to research your local regulations and always choose nursery-grown plants over wild collection to help preserve wild populations of this special native species.
