Correll’s Buckwheat: A Hidden Gem for Texas and Oklahoma Native Gardens
If you’re looking for a native plant that’s both beautiful and resilient, Correll’s buckwheat (Eriogonum correllii) might just be the perfect addition to your garden. This charming perennial herb brings delicate beauty to drought-prone landscapes while supporting local wildlife—though there are a few important things to know before you plant it.
What Makes Correll’s Buckwheat Special?
Correll’s buckwheat is a true native of the American Southwest, calling only Texas and Oklahoma home. This makes it perfectly adapted to the challenging conditions of the region, from scorching summers to unpredictable rainfall. As a perennial forb, it returns year after year without developing woody stems, making it an excellent low-maintenance ground cover option.
The plant produces clusters of small white to pinkish flowers that create a delicate, cloud-like appearance when in bloom during late spring and early summer. These modest but beautiful blooms sit atop low-growing foliage, typically reaching just 6-12 inches in height.
Where Does It Grow Naturally?
Correll’s buckwheat has a relatively small native range, growing wild in north-central Texas and south-central Oklahoma. In nature, you’ll find it thriving in limestone soils and rocky areas where many other plants struggle to survive.
