If you’ve ever dreamed of adding a splash of sunshine to your drought-tolerant garden, meet sulphur-flower buckwheat (Eriogonum umbellatum var. speciosum). This California native perennial might just become your new favorite plant, especially if you love low-maintenance beauties that attract pollinators while conserving water.
What Makes Sulphur-Flower Buckwheat Special?
