Common names include desert marigold, showy desert marigold, paper daisy, desert baileya, and hierba amarilla. Synonyms include Baileya australis, Baileya multiradiata var. nudicaulis, Baileya multiradiata var. thurberi, and Baileya thurberi. The genus is named after American botanist Jacob Whitman Bailey; “multiradiata” refers to the many-rayed flower heads.
Description
Desert marigold is a native, sun-loving biennial or short-lived perennial forb/herb that typically grows 12–18 inches (30–52 cm) tall and spreads 4–12 inches (10–30 cm) wide, forming attractive mound-shaped clumps. The basal leaves are grayish-green, woolly (covered in soft white hairs that help retain moisture), pinnately lobed to entire, and clustered at the base (4–10 cm long). The stems are mostly leafless and branched in the lower half. Flower heads are solitary, daisy-like composites borne on long, naked stalks (10–32 cm). Each head measures about 1.5–2 inches (4–5 cm) across with 25–50 bright yellow ray florets (the “petals”) surrounding a central disk of 25–50+ yellow disk florets. As the flowers age, the rays fade and become papery, giving rise to the common name “paper daisy.” The plant is adapted to arid conditions and is distinguished from similar species like woolly desert marigold (Baileya pleniradiata) by its taller stature, longer bloom period, and greater abundance.
Blooms
The showy, bright-yellow composite flower heads bloom intermittently from March (or April) through November, and can continue year-round in favorable conditions with adequate moisture. Flowering is sporadic but prolific, often triggered by rainfall, producing impressive mounds of nearly solid yellow. The long-lasting blooms turn papery and persist on the plant as they age. This extended blooming period makes it one of the most reliable and conspicuous desert wildflowers.
Range and Distribution
Desert marigold is native to the Mojave, Sonoran, and Chihuahuan deserts of the southwestern United States and northern Mexico. In the U.S., it occurs in Arizona, California, Nevada, New Mexico, Texas, and Utah (primarily at lower to mid-elevations). In Mexico, it extends into states including Sonora, Chihuahua, Coahuila, Durango, and Aguascalientes. It grows on sandy or gravelly (often alkaline) soils in washes, roadsides, rocky slopes, sandy plains, mesas, and semidesert grasslands, from near sea level up to about 5,000–6,500 ft (100–1,981 m). It thrives in full sun and well-drained soils across desert ecosystems.
This hardy, drought-tolerant wildflower is an iconic component of southwestern desert landscapes, valued for its cheerful blooms and adaptability.
