Apalachicola St. Johnswort: A Rare Florida Wetland Gem Worth Protecting
Meet the Apalachicola St. Johnswort (Hypericum chapmanii), a charming yet vulnerable native shrub that calls Florida’s panhandle home. This little-known member of the St. John’s wort family might just be the perfect addition to your wetland garden—if you can find it responsibly sourced, that is.
A True Florida Native with a Story
The Apalachicola St. Johnswort is as Floridian as it gets, being native to the lower 48 states with its entire natural range concentrated in Florida. This perennial shrub has adapted to thrive in the unique wetland ecosystems of the Sunshine State, making it a true regional treasure.
Why This Plant Deserves Your Attention (And Caution)
Before you get too excited about adding this beauty to your garden, there’s something important you need to know: Hypericum chapmanii has a Global Conservation Status of S3, meaning it’s considered vulnerable. With only 21 to 100 occurrences and between 3,000 and 10,000 individuals remaining, this plant is quite rare. If you’re considering growing it, please ensure you source it from reputable native plant nurseries that propagate it responsibly—never collect from the wild.
What Makes It Special
This delightful shrub typically grows as a multi-stemmed woody plant, usually staying under 13-16 feet in height. Like other members of the St. John’s wort family, it produces cheerful yellow flowers that bloom during the summer months, creating a bright splash of color in wetland settings. The flowers are particularly beloved by bees and other pollinators, making this plant a valuable addition to pollinator-friendly gardens.
Perfect for Wetland Gardens
Here’s where things get interesting: the Apalachicola St. Johnswort is classified as an Obligate Wetland plant in the Atlantic and Gulf Coastal Plain region. This means it almost always occurs in wetlands and requires consistently moist to wet growing conditions. If you’re planning a rain garden, bog garden, or wetland restoration project, this could be your star player.
Growing Conditions and Care
Successfully growing Apalachicola St. Johnswort requires mimicking its natural wetland habitat:
- Sunlight: Full sun to partial shade
- Soil: Consistently moist to wet soils
- Hardiness Zones: 8-9 (ideal for Florida and similar climates)
- Water needs: High – this plant loves having wet feet
Is It Right for Your Garden?
The Apalachicola St. Johnswort isn’t for every gardener or every garden. You should consider planting it if:
- You’re creating a wetland or bog garden
- You want to support conservation of rare native plants
- You have consistently wet areas in your landscape
- You’re working on pollinator habitat in wetland settings
- You can source it from responsible native plant nurseries
However, this plant might not be suitable if you have typical garden conditions with well-draining soil or if you’re looking for a low-maintenance, drought-tolerant option.
A Plant Worth Protecting
By choosing to grow Apalachicola St. Johnswort responsibly, you’re not just adding a unique native plant to your garden—you’re participating in conservation efforts. Every garden that provides habitat for rare native plants like this one helps ensure their survival for future generations.
Remember, with great beauty comes great responsibility. If you decide to grow this rare gem, make sure you’re sourcing it ethically and providing the specialized wetland conditions it needs to thrive. Your garden could become a small sanctuary for one of Florida’s most vulnerable native plants.
