Sulfur Flower (Eriogonum umbellatum): Long-Blooming Native for Dry Gardens

Sulfur flower (Eriogonum umbellatum) is a star of drought-tolerant Western landscapes. This long-lived perennial offers wonderful evergreen foliage and brilliant yellow blooms from late spring through late summer. Remarkably adaptable, it even thrives in humid climates.

Growing Requirements

Provide full sun and poor, gritty, sharply drained soil. Seeds are oblong and nutlike—sow in winter for April/May seedlings that become husky plants by summer's end.

Potential Issues

Watch for powdery mildew, rust, spider mites, and aphids.
