This unassuming little annual packs a punch when it comes to drought tolerance and wildlife value, making it a smart choice for water-wise landscaping in the American Southwest.
What Is Flatcrown Buckwheat?
Flatcrown buckwheat is a native annual forb that belongs to the buckwheat family. Don’t let the name fool you – this isn’t related to the grain we eat for breakfast!

Growing Conditions and Care
The beauty of flatcrown buckwheat lies in its simplicity. This plant thrives in conditions that would stress many garden favorites:
- Sunlight: Full sun is essential
- Soil: Well-draining sandy or rocky soils preferred
- Water: Minimal once established; excellent drought tolerance

Planting and Establishment Tips

Is Flatcrown Buckwheat Right for Your Garden?
This native annual is ideal if you’re gardening in the southwestern United States and want to create a sustainable, low-water landscape that supports local wildlife. It’s particularly valuable for gardeners dealing with poor soils, slopes, or areas where irrigation is challenging or undesirable.
