From the maritime provinces of Nova Scotia down to the coastal states, you’ll find Jesuit’s bark thriving in Connecticut, Delaware, Georgia, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New York, North Carolina, Pennsylvania, Rhode Island, Texas, and Virginia.

Why Consider Jesuit’s Bark for Your Garden?

Here’s where Jesuit’s bark really shines – it’s a native plant that supports local ecosystems while requiring minimal fuss from gardeners. As a perennial, it’ll return year after year, establishing itself as a reliable presence in your landscape.

The plant’s forb nature means it won’t compete with trees and shrubs for space, making it an excellent choice for:

  • Native plant gardens
  • Naturalized landscapes

Then Jesuit’s bark could be an excellent choice. However, we recommend doing additional research specific to your growing zone and consulting with local native plant societies or extension offices for the most current cultivation information.
