Tag: Arizona

Arizona, located in the southwestern region of the United States, is renowned for its diverse landscapes and cultural richness. Home to iconic natural wonders such as the Grand Canyon, Monument Valley, and the red rocks of Sedona, Arizona offers a dramatic and varied terrain that ranges from arid deserts to pine-covered mountains. The state’s climate is typically characterized by hot summers and mild winters, with the southern parts being desert-like while the northern regions experience a more temperate climate. Arizona is also rich in Native American history, with numerous tribes such as the Navajo, Hopi, and Apache having deep roots in the region. The state’s cities, including Phoenix and Tucson, blend modern urban life with a strong appreciation for the natural environment and cultural heritage. Arizona’s economy thrives on tourism, technology, and agriculture, making it a dynamic and multifaceted state.

Biological Report: Desert Marigold

Scientific Taxonomy

  • Kingdom: Plantae
  • Clade: Tracheophytes
  • Clade: Angiosperms
  • Clade: Eudicots
  • Clade: Asterids
  • Order: Asterales
  • Family: Asteraceae (Aster or Sunflower family)
  • Genus: Baileya
  • Species: Baileya multiradiata Harv. & A. Gray ex A. Gray

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.

This yellow wild flower is also known as:

  • Desert Marigold
  • Showy Desert Marigold
  • Paper Daisy
  • Desert Baileya

Desert Primrose (Oenothera deltoides)

Classification (Taxonomy)

Oenothera deltoides belongs to the evening primrose family and is classified as follows (using a combination of traditional Linnaean ranks and modern phylogenetic clades):

  • Kingdom: Plantae
  • Clade: Tracheophytes (vascular plants)
  • Clade: Angiosperms (flowering plants)
  • Clade: Eudicots
  • Clade: Rosids
  • Order: Myrtales
  • Family: Onagraceae Juss. (Evening Primrose family)
  • Genus: Oenothera L.
  • Species: Oenothera deltoides Torr. & Frém. (described in 1845 by John Torrey and John C. Frémont)

The species includes several subspecies (e.g., O. d. subsp. howellii, which is federally endangered in California, and others such as subsp. deltoides, subsp. piperi, subsp. ambigua, subsp. cognata, and subsp. julpunensis). The overall species is considered secure.

Description

Oenothera deltoides, commonly known as the Desert Primrose, is a bushy or mounded annual (sometimes short-lived perennial) herb in the Evening Primrose family. It typically grows 2–18 inches (5–46 cm) tall but can reach up to 3 feet (about 1 m) in favorable conditions, with a spread up to 40 inches (1 m) wide. The plant often forms a dense basal rosette with a central erect stem and several decumbent to ascending leafy branches. The herbage is grayish-green to pale green and may be hairy or glandular.

Leaves: Primarily basal and sparse along the stems; deltoid (triangular) to obovate or oblanceolate in shape, up to 4 inches (10 cm) long. Margins are often toothed, lobed, grooved, or cleft, giving a distinctive triangular appearance (reflected in the species epithet deltoides).

Flowers: Large, showy, and fragrant, measuring 1.5–3 inches (4–8 cm) wide with four white petals forming a saucer or cup shape (sometimes turning yellowish toward the center). They open in the early evening (around sunset) and close by mid-morning, a classic evening-primrose trait. The flowers are solitary in the upper leaf axils and fade to pinkish with age. They are pollinated primarily by nocturnal moths (such as the white-lined sphinx moth) and native bees.

Fruit: A woody capsule that persists after flowering.

Distinctive Feature: After the plant dies (typically after setting seed), the stems curl upward and inward, forming a hollow, cage- or basket-like structure. This gives rise to many of its common names and allows the dried plant to tumble in the wind, dispersing seeds.

The plant is highly adapted to arid conditions and often carpets sandy desert floors with white “tissue-paper-like” blooms following abundant winter rains.

Range and Distribution

Oenothera deltoides is native to the Southwestern United States and northern Mexico. Its range includes the Mojave and Colorado Deserts, extending into parts of the Great Basin and coastal sandy areas. It occurs in the following U.S. states: Arizona (AZ), California (CA), Nevada (NV), Oregon (OR), and Utah (UT). In Mexico, it is found in northern Baja California and northwestern regions.

Habitat: Dry, open sandy soils, dunes, desert washes, rocky cliffs, hillsides, and occasionally beaches or coastal dunes. Elevations are generally below 2,500–5,500 feet (760–1,680 m), depending on the region. It thrives in full sun and is most abundant in the Mojave, Sonoran, and adjacent desert regions after wet winters.

Flowering season is primarily January–May (varying slightly by location and rainfall), with peak blooms often in February–April.

List of Other Common Names

In addition to Desert Primrose (or Dune Primrose), the species is known by many evocative names that reference its flowers, fragrance, or post-death “cage” structure:

  • Birdcage evening primrose
  • Basket evening primrose
  • Birdcage primrose
  • Dune evening primrose
  • Lion in a cage (or Lion-in-a-cage)
  • Devil’s lantern (or Desert lantern)
  • Fragrant primrose
  • Desert evening-primrose
  • Hairy evening primrose (occasional reference)

These names vary regionally but consistently highlight the plant’s striking appearance and unique dried form.

Oenothera deltoides is a beautiful and ecologically important desert wildflower, providing nectar for pollinators and contributing to the spectacular spring displays of the American Southwest. It is widely available for native plant gardening in arid regions and requires well-drained sandy soil with minimal irrigation once established.

Owl’s Clover (Castilleja exserta)

Posted on by

Owls Clover (Castilleja exserta) is a small flowering plant which can grow about 1 foot tall.   The Owl’s Clover is a native plant to California, Arizona, New Mexico and the Northwestern areas of Mexico.  Like other Castilleja plants, which also includes the Indian Paintbrushes, the Owl’s Clover is hemiparasitic which means that it obtains its nutrients from the roots of other plants.

The Owls Cover blooms from March to May and may be found at elevations from 2000 ft to 3000 ft. The plant ranges in height from 4 to 18 inches in height. The underdeveloped, hairy stemmed leaves are threaded in appearance because they are not needed for nutrients or photosynthesis. Rather, the roots of this plant will growth into the root structures of other plants around it, stealing the nutrients from it.

The thin, erect bracts are usually tipped in the same color. This will give the flower a dual tone color and the appearance a paintbrush dipped in paint. This is the source of the the paintbrush common name of other plants in this genus.

The seeds of the Owl’s clover were harvested and utilized as a food source by the indigenous peoples of California.

Lower Antelope Canyon

Lower Antelope Canyon one of two slot canyons located off the highway 98 just outside of Page, Arizona near the Utah border.

Entering Lower Antelope Canyon
Entering Lower Antelope Canyon

Slot Canyons are formed in usually arid regions, where a little bit of rain falls, and fulls the dry rivers of the desert southwest.  The water can flash flood, which picks up speed and debris and scours the landscape.  Overtime, the water forces itself into cracks in the rock and widens the deepens the crack into a deep narrow canyon.   Lower Antelope is a commonly overlooked when compared the Upper Antelope Canyon, although does seem to be gaining in popularity.

Hasdestwazi, or “spiral rock arches ” as it is known to the LeChee Chapter of the Navajo Nation, Lower Antelope slowly exposes itself to you as a small crack in the rock which grows slightly in width, and dramatically  in depth as you climb down into the slot canyon.

Unlike Upper Antelope Canyon which is an easy walk, Lower Antelope Canyon is a steep and deep trail as the passage plunges deeper into the rock.  The Navajo Nation is kind enough to maintain metal stairs to aid the trek, however on my last visit the stars where covered in mud, silt and debris from a recent storm which further sculpts the rock.   Upper Antelope pulls you eyes up into the colorful light above, however there is no real sense of depth.  Lower Antelope Canyon constantly reminds you how deep you really are beneath the surface.

The stairs inside of lower Antelope Canyon show signs of a recent flood.

Just like Upper Antelope Canyon, a narrow opening at the top of the canyon only allows a little light the enter the canyon.  This light bounces off the canyon walls, and throughout the day, a light show of glowing rock, shadows and textured water sculpted rock offer a wonderful visuals to the visitors.

The sculpted rock and light offer beauty, texture and scenic photographic opportunities, however this beauty hides a danger.  An August 12, 1997 a group of eleven tourists where killed inside the canyon when a flash flood filled the canyon in seconds.  A sole tour guide survived the tragedy.

As I follow the canyon down towards Lake Powell in the distance, I would constantly find my self touching the smooth canyon rock walls, all the while knowing that a summer monsoon miles aware could end my time on this planet.  However, although always a bit uneasy, it is an amazing place and well worth the trip and the remote risk.

The Green Gopher

Posted on by

Growing up in the 70’s I learned and spent a lot of time camping, hiking, being outdoors and active.  Every spring summer and fall, my parents and I would load up the truck, and later the trailer and head out.  Typically preparations would start the week before departure, and the loading process would start on Thursday afternoon with my brother and I hauling all the gear into the yard, while my mom packed the vehicles.  Friday could not come soon enough and when it did, my dad would come home from work, change is clothes, wrangle up two kids, maybe a dog, adjust the mirrors, and exclaim “We’re off” as we drove out of the driveway in The Green Gopher.  For the most part, for my family nothing much has changed much from my dad.  It is however the details that matter.

In 1972, I was one year old and to celebrate my dad bought a new truck.  Details of the vehicle back then are scarce.  From my point of view, my dad previously owned a 1964 International Scout.  He drive this car for years all over the desert south west in the late 1960s.  When my dad married my mom, my mom made him sell the Scout because the breaks were horrible, and at least three times they failed completely.  It was a wise decision considering the stakes for the family at the time, but the loss of his beloved Scout was difficult and for decades despite its faults the Scout cast a long shadow in our family.

Returning to 1972, my dad decided to purchase his truck.  He chose a Sea Foam Green 1972 Ford F-100 pickup sporting a 302 inch V-8 sporting with a 3.2:1 gear ratio, two fuel tanks, and a four speed manual transmission which included a “Granny Gear”.  The extra costs of a four wheel drive were not an option for my dad at that time.  So, the truck became the “ultimate compromise”.  He opted for 2 wheel drive, but to offer improved traction he chose a four speed with granny gear.  The differential was geared up to offer improve gas mileage, but the little 200 HP V-8 could not pull a grade at any sort of highway speeds.  A camper shell, home built bed, pass-through rear window and the “green gopher” was complete for the initial incarnation.
