Weatherby’s Arrowhead: A Rare Native Gem for Your Wetland Garden
If you’re looking to add some authentic southeastern charm to your wetland garden, meet Weatherby’s arrowhead (Sagittaria graminea var. weatherbiana) – a delightful native perennial that’s as beautiful as it is ecologically important. This lesser-known member of the arrowhead family brings both aesthetic appeal and conservation value to the right garden setting.
What Makes Weatherby’s Arrowhead Special?
Weatherby’s arrowhead is a native perennial forb that calls the southeastern United States home. As an obligate wetland plant, it’s perfectly adapted to life in constantly moist conditions and shallow water. The plant produces charming small white flowers with three delicate petals that dance above the water’s surface, creating a lovely contrast against its distinctive arrow-shaped foliage.
This plant is also known by its scientific synonyms Sagittaria graminea ssp. weatherbiana and Sagittaria weatherbiana, so don’t be confused if you see it listed under these names at specialty nurseries.
Where Does It Grow Naturally?
Weatherby’s arrowhead is native to five southeastern states: Florida, Georgia, North Carolina, South Carolina, and Virginia. It thrives in the wetland habitats of both the Atlantic and Gulf Coastal Plain regions as well as the Eastern Mountains and Piedmont areas.
A Word About Rarity
Here’s something important to know: Weatherby’s arrowhead has a Global Conservation Status of S5T3T4, which indicates some level of conservation concern. If you’re interested in growing this beautiful native, please make sure you source it responsibly from reputable native plant nurseries that propagate their own stock rather than wild-collecting. This helps protect wild populations while still allowing you to enjoy this special plant in your garden.
Perfect Growing Conditions
As an obligate wetland species, Weatherby’s arrowhead has very specific needs:
- Moisture: Requires constantly moist soil or shallow standing water
- Light: Thrives in full sun to partial shade
- Hardiness: Suitable for USDA zones 6-9
- Soil: Adaptable to various wetland soil types
Ideal Garden Settings
This isn’t a plant for your average perennial border! Weatherby’s arrowhead shines in:
- Pond margins and water gardens
- Bog gardens
- Rain gardens (if consistently moist)
- Wetland restoration projects
- Native plant gardens with water features
Wildlife and Pollinator Benefits
Those lovely white flowers aren’t just pretty – they’re pollinator magnets! Various bees, flies, and other beneficial insects visit the blooms for nectar and pollen. As a native wetland plant, it also provides habitat and food sources for wetland wildlife and contributes to the overall health of aquatic ecosystems.
Planting and Care Tips
Growing Weatherby’s arrowhead successfully is all about meeting its moisture needs:
- Planting time: Spring is ideal for establishment
- Water requirements: Never let it dry out – constant moisture is essential
- Maintenance: Minimal once established in the right conditions

Is Weatherby’s Arrowhead Right for Your Garden?
This charming native is perfect for gardeners who:
- Have naturally wet areas or water features in their landscape
- Are interested in wetland restoration or native plant conservation
- Want to support local pollinators with native plants
- Appreciate unique, lesser-known native species
However, it’s not the right choice if you have typical garden conditions with well-draining soil, as it simply won’t survive without constant moisture.
Remember, when you choose to grow Weatherby’s arrowhead, you’re not just adding beauty to your garden – you’re participating in the conservation of a special southeastern native plant. Just make sure to source it responsibly, and enjoy watching this delightful wetland gem flourish in your water garden!
