Utah, a state in the western United States, is renowned for its stunning natural landscapes and unique geological formations. It is characterized by vast deserts, towering red rock formations, and the dramatic peaks of the Rocky Mountains. Home to five national parks—Zion, Bryce Canyon, Capitol Reef, Canyonlands, and Arches—Utah attracts outdoor enthusiasts and nature lovers from around the world. Its capital, Salt Lake City, is a hub of culture, history, and outdoor recreation, famously hosting the 2002 Winter Olympics. Utah’s diverse terrain offers opportunities for skiing, hiking, mountain biking, and exploring ancient Native American petroglyphs and archaeological sites. The state’s Mormon heritage is also evident in its history, architecture, and the world-famous Salt Lake Temple.

Joshua Tree (Yucca brevifolia)

Posted on by

The Joshua Tree was named for the biblical character by the Mormon Setters as they crossed the Mojave Desert in the mid 19th century.  It is told that the tree reminded the early Mormon’s of Joshua who, much like the tree, held his hands up in prayer.  From these humble beginnings, this tree and its undulating shadows have become of an icon of the desert southwest.

Joshua Trees are found in the desert southwest at elevations between 1300 and 5900 feet.  A member of the Yucca family, the Joshua can live several hundred years and grow up to 30 feet tall and have a trunk up to 3 feet in diameter.  The tree trunk contains many small fibers and does not contain growth rings as with typical trees.  A top heavy branched tree it can develop an impressive and deep root system which can reach 31 feet deep.

During the spring months of February, March and April, white flowers signal be beginning of spring for the Joshua Tree.  Flowering is dependent upon both an adequate amount of rain and a freeze.  Once flowered, the Joshua Tree is dependent upon the Yucca month for pollination.

New trees can develop from the roots of existing tree from Rhizomes, however the Yucca moth is required to create new stands of trees from the seeds.

This yucca plant inspired a National Park in Southern CA, which is a favorite location to visit.  The symbol of the high desert, the tree is the name sake of a famous Irish rock band, which is also a favorite.

Bristlecone Pine (Pinus longaeva)

Posted on by

Blown by wind, and ravaged by time, the Bristlecone pine tree is a silent sentinel of the White Mountains in eastern central California.  Only growing high in subapline mountains, Bristlecone pine trees are among the oldest living organisms, reaching ages of 5000 years old, with on specimen being documented at 5,067 years old by Tom Harlan who aged the tree by ring count.  That calculation confirms this one individual tree to be the oldest living non-clonal organism on the planet.

The Bristlecone pine groves are found between 5,600 and 11,200 ft of elevation on mountain slopes with dolomitic coils and can be reached using the White Mountain Road.  This harsh alkaline soil gives the Bristlecone a competitive advantage because over plants and tree are unable to grow.  The trees grow very slowly due cold temperatures, arid soil, wind and short growing seasons.

Reaching a maximum height of 49 ft with a truck diameter up to 12 ft, the Bristlecone pine maintains a bright orange or yellow.  The stunted, twisted and gnarled trees contain deep fissures which expose deep orange bands of wood within the tree.  The waxy needles are bunched in groups of five and form at the end of branches and also aid in water conservation.  The Bristlecone wood is resistant to insects, fungi and other pests which may shorten its lifespan, due to the density of its wood and relatively high resin content.  The harsh environment the tree grows in undoubtedly contributes.  Unlike most trees which rot with age, the wood of this tree is contorted and eroded from sand, high winds, rain and ice.  The age of these tree and harsh conditions cause the trees to twist and contort into other-worldly forms.

As with many species, the Bristlecone is uniquely qualified to thrive in its selected climate.  The tree maintains a shallow highly branched root system which not only brings in water from the soil around it, but also anchors the tree the the side of the mountain.  Its dense wood which protects from insects, also protects from the winds.  Although the Bristlecone pine population is stable, it is being monitored as a species of Least Concern due to its slow rate of growth, low reproduction rate, harsh environment and environmental concerns.

The age of these trees is story of these gnarled trees.  Although fantastic photographic subject, they are not particularly nice looking trees.  They tend to be rather short, not very green and in some cases appear to be mostly dead or dying.  However, they hold the top three on the list of oldest living  trees and are aged about 1000 years over the fourth ranked tree.  The third ranked tree, Prometheus, was cut down in by a graduate student in 1964 and the U.S Forest Service, because they did that sort of thing back then.  Prometheus was 4844 years old on its death and due to its location in Baker Nevada could be a trip in the next few years.  Over fifty years since the tree was killed, it is easy to second guess the decision with hind-sight and an environmental outlook that did not exist as much back then.  Science is not always clean and neat.

The second tree on the list is Methuselah at 4849 years of age at was the oldest tree until 2012 when an older tree was found.  The unidentified and unnamed oldest tree was 5,067 years old by Tom Harlan calculated its age in 2012.  This tree was around before the oldest pyramid of Egypt, the Pyramid of Djoser which was built in the 27th century B.C.

One a personal note, I can not remember when I didn’t know about the old trees in the white mountains.  I don’t remember my first visit, but I will never forget my last.  The wonderful part of these trees, is that their small environments are so remote and high in the mountains.  The trees are special and should be seen.  Walked through.  Appreciated.  Unlike other large tree groves, such as the Redwoods of Yosemite, the Bristlecone pine groves of the White Mountains, CA, are not as visited.  Which means that you can visit the trees and be alone without the throngs of people.  Finally, when you are done and turn back towards the car, if you are in the White Mountains, you get some of the most amazing view of the Owens valley below you.

Beavertail Prickly Pear (opuntia basilaris)

Posted on by

The Beavertail Prickly Pear cactus (opuntia basilaris) is very common in the desert south west, and would go most of the year most of the year without a second glance.  However this species of cactus exemplifies the best of what the desert has to offer in one symbol.

The Beavertail Prickly Pear grows in clumps, low to the ground and grows horizontally rather than vertically like the iconic saguaro.  The dull greenish grey leaves grows feature a complete lack of spines and a shaped which gives the plant it’s name.  The pads of this cactus lake the spines traditionally associated with cactus, but rather the pads are covered with minuscule, gray-blue bristles which feature barbed tips which easily puncture human skin.

Each spring the cactus puts on a display of wild flowers which is amazing to behold in the arid desert environments.  Typically starting the March, each cactus pad my put out several shoots which Colosseum in a burst of colors, most commonly a vibrant pink but also known to be yellow, white or rose colored.

Spreading Phlox ( Phlox diffusa )

Posted on by

Spreading Phlox ( Phlox diffusa ) is a perennial shrub with small needle like leaves.  This is a small white flowering plant prefers alpine, sub-alpine environments and rocky or sandy soil.  This is a low growing plant which is commonly only two to eight inches tall which probably offers survival advantages when confronted with the harsh landscapes of sub-alpine and alpine environments, in which it thrives.

Spreading Phlox is commonly found and adapted high in the mountains and distributed throughout in the western United States and Canada. This plant employs a tap route, which is ideally suited to capture water deeper under ground and also offers an anchor to help the plant cling to the mountain in high wind conditions. The plant is short, and when in full bloom, the flowers may completely obscure the green needle like leaves from view.

The five petaled flowers range in color from a clean, magnificent white to calming understated lavender or pink color.  

The blooms are typically visible from May to August and a welcome sight to those who hike at elevation.

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
