Dogtongue Buckwheat: A Charming Native Ground Cover for Southern Gardens
If you’re looking for a low-maintenance native plant that adds subtle beauty to your landscape while supporting local wildlife, dogtongue buckwheat (Eriogonum tomentosum) might just be your new garden favorite. This delightful perennial forb brings a soft, textural element to gardens across the Southeast with its fuzzy leaves and delicate flower clusters.
What is Dogtongue Buckwheat?
Dogtongue buckwheat is a native perennial forb, meaning it’s a non-woody plant that returns year after year. As a member of the buckwheat family, it produces small, clustered flowers that create a gentle carpet of blooms during its flowering season. The plant gets its common name from its distinctively shaped, tongue-like leaves that are covered in a soft, woolly coating called tomentum—hence the scientific name tomentosum.
Where Does It Grow Naturally?
This southeastern native calls five states home: Alabama, Florida, Georgia, North Carolina, and South Carolina. In these regions, you’ll typically find dogtongue buckwheat growing in sandy soils, open woodlands, and coastal areas where it has adapted to thrive in well-draining conditions.
Why Choose Dogtongue Buckwheat for Your Garden?
There are several compelling reasons to consider adding this native beauty to your landscape:
- Pollinator magnet: The small flowers attract bees, butterflies, and other beneficial insects, making it an excellent choice for pollinator gardens
