Angelita Daisy (Tetraneuris acaulis): A Tough, Long-Blooming Native for Western Gardens

Few perennials deliver as much cheer with as little fuss as angelita daisy (Tetraneuris acaulis, formerly Hymenoxys acaulis). Native to the American Southwest, this compact, mounding plant produces a near-constant parade of sunny yellow, daisy-like flowers above dark green, grass-like foliage. In USDA zones 8 and above, it blooms year-round; in cooler zones (5–7), it goes dormant in winter and returns vigorously each spring.

Distinguishing Traits

Each 1-inch flower sits atop a leafless stem, creating a tidy, bouquet-like effect. The narrow, evergreen leaves form a dense, low cushion that stays attractive even when bloom slows. In low-desert regions, flowering is nearly continuous, with a peak in spring. At higher elevations, the plant pauses in winter but rebounds quickly as temperatures rise.

Design Applications

Angelita daisy shines when planted in drifts of three to five. Use it to soften boulders, line pathways, or add a pop of yellow to succulent beds. Its bright flowers make neighboring colors — especially blues, purples, and reds — appear more vivid. Excellent companions include agave, purple prickly pear (Opuntia violacea var. santa-rita), firecracker penstemon (Penstemon eatonii), and Baja fairy duster (Calliandra californica). It also thrives in containers and poolside plantings, where its tidy habit and long bloom season shine.

Planting and Maintenance

• Soil: Well-drained; avoids heavy clay.
• Water: Supplemental irrigation during establishment; then occasional deep soakings.
• Fertilizer: Not needed; performs best in lean soil.
• Pruning: Shear spent flowers every few months to stimulate new buds.

This Southwest native handles full, reflected sun and brutal cold with equal aplomb, making it a reliable, low-maintenance star for almost any sunny garden.
