Munz’s Buckwheat: A California Native Worth Adding to Your Garden

If you’re looking for a drought-tolerant perennial that supports local wildlife while adding unique charm to your California landscape, Munz’s buckwheat (Eriogonum umbellatum var. munzii) might just be the perfect addition to your garden. This lesser-known native gem belongs to the diverse buckwheat family and offers gardeners a chance to cultivate something truly special.

What Makes Munz’s Buckwheat Special?

As a variety of the more widespread sulphur-flowered buckwheat, this particular form has adapted specifically to California’s unique growing conditions. It’s what botanists call a forb, which simply means it’s a flowering plant that isn’t a grass, shrub, or tree.
