  • One of my favorite desert wildflowers, the desert globe mallows are often seen along roadsides, such as this one in rural Pima County in Southern Arizona, deep in the Sonoran Desert.

  • A common native plant and wildflower found in deserts, prairies and other open dry habitats, the desert prince's plume is a member of the mustard family. It can be found in every western continental state excluding Oklahoma, Washington and Alaska, and does not appear to grow in any of the Canadian provinces. This was photographed in California's Mojave Desert in Joshua Tree National Park.

  • These very small and extremely vibrant blue wildflowers are a member of the borage family. Also known as scorpionweed, I photographed these beauties in an arroyo I wandered into in Southern California in the Mojave Desert.
    Desert Bluebells
  • Desert bluebells growing along Highway 86 in southern Arizona in Pima County. These tough and beautifully compact wildflowers bloom in the early springtime in the harshest of desert environments soon after the spring rains begin.

  • Desert lupine (also known as arroyo lupine or Coulter's lupine) is found across most of Southern Arizona at low elevations under 3000'. This amazing member of the pea family has a cool adaptation to direct bees to the best flowers: once a new flower opens and a bee comes in contact with it while collecting the pollen, the yellow spot turns red, letting any pollinators know that that flower has already been visited. These lupines were found growing on the side of the road outside of Sells, AZ in Pima County.

  • The fishhook barrel cactus is a rather common large barrel cactus found in the Sonoran and Chihuahuan Deserts of the American Southwest with a range stretching from Arizona through New Mexico to Texas, as well as south of the border into the northern parts of the Mexican states of Sonora and Chihuahua. Bright yellow fruit emerge and develop throughout the year after its bright orange blossoms are pollinated in summer, and by the following spring they will look like this. As with many cacti, it has many regional names such as the Arizona barrel and biznaga-barril de Nuevo México and is found in open rocky ground, shrub-steppe, chaparral and at the base of desert hills and mountains where there is some gathering of water during seasonal rains. Mature plants can reach upwards of 5 feet tall, and live to 50 to 130 years, and as they get larger, they will tend to lean to face south or southwest-ward, which is why come people also call it the compass cactus. Vicious recurved spines (or "fishhooks") protect it from predators such as javelinas, and the fleshy yellow fruits are an important food source for birds, mule deer, and javelinas. This one was found and photographed between the Ajo and Puerto Blanco Mountains ranges in the Sonoran Desert in Southern Pima County, Arizona.

  • A favorite food source for hummingbirds in the Sonoran Desert, Parry's penstemon (also known as Parry's beardtongue) is a vibrantly pink to fuchsia hardy wildflower found natively in Southern Arizona and Northern Mexico. These tough plants can stand the heat of the desert and the heavy spring rainfalls typical of our southwestern deserts and are only bested by prolonged drought. These were among about a dozen beautiful tall blooming examples found growing in the hills of rural Santa Cruz County in southern Arizona.

  • From personal experience, the teddybear cholla (named for the thick, bristling spines that almost look like soft fur) are a real eye-opener when one first makes physical contact with this native of the American Southwest. Casual passing contact will not only cause immense sharp pain, but the piece of the cactus touched will detach from the main part of the plant and tag along for the ride. This evolutionary and reproductive tactic is why this cholla is often called the "jumping cholla" - it will hop a ride with anything that touches it, eventually fall to the ground and once it roots, grow a whole new cactus. These were found and photographed<br />
growing (without touching) in the open Sonoran Desert in the Picacho Peak Wilderness Area in Southern California's rural Imperial County.

  • The Arizona fishhook cactus (also known as Graham's nipple cactus) is not only limited to Arizona, but is  also found in California, New Mexico and Texas, as well as much of Northern Mexico. One of the most interesting things about this particular native species of the Sonoran and Chihuahuan Deserts are the recurved "fishhook" spines. This one was found in Southern Arizona's Diablo Mountains near the Mexican border.

  • The venomous, yet slow-moving gila monster posing in the lower branches of a mesquite bush in the Sonoran Desert, just outside of Tucson, Arizona. This was my first time seeing one in the wild, and I actually delayed my travel plan to spend extra time looking for one of these.

  • Early morning just as the desert sun blasts the Mojave Desert in bright light, these Mojave mound cacti clearly show the distinct reddish-pink spines they are known for. This is one of the toughest of all desert cacti, and unlike most species that bloom right after the spring rains, this one waits until the hottest part of summer to blossom. No wonder it is thrives in the hottest locations in the country.

  • Sometimes referred to as beargrass, this native desert species is actually a member of the lily family, even though it has a striking resemblnce at first to members of the yucca family. Found primarily in the Mojave Desert of Southern California, it is also found in limited numbers in Arizona's Sornoran Desert. Unusual for plants that grow in very dry, arid locations, the Bigelow's nolina is one one of the very few evergreen plants that grows in it's habitat. This group of flowering nolinas were photographed in Califonia's Joshua Tree National Park in the early spring morning sunlight.

  • Still a small cluster of Mojave mound cacti, this grey-green species of barrel cactus with their distinctive dusty pink spines normally is found in clumps of 20-40 stems. Also known as a cottontop cactus (you can see what appears to be a ball of cotton at the top of each one), in June or July in the hottest part of the desert summer, a bright yellow blossom will flower. These were found and photographed while I was searching for some shade in the Mojave desert.

  • Considered to be one of the desert's oldest living plants, a mature Joshua tree is believed to be between 150-300 years old, and one specimen that reached a height of a whopping 60 feet was believed to have been about 1000 years old! This much younger one was photographed in Southern California's Mojave Desert.

  • From personal experience, the teddybear cholla (named for the thick, bristling spines that almost look like soft fur) are a real eye-opener when one first makes physical contact with this native of the American Southwest. Casual passing contact will not only cause immense sharp pain, but the piece of the cactus touched will detach from the main part of the plant and tag along for the ride. This evolutionary and reproductive tactic is why this cholla is often called the "jumping cholla" - it will hop a ride with anything that touches it, eventually fall to the ground and once it roots, grow a whole new cactus. This one was found growing (without touching) along the side of a dried-out arroyo in a nameless canyon in Southern California's Anza-Borrego Desert in San Diego County.

  • The brown-spined prickly pear (also regionally known as the tulip or desert prickly pear) is another widespread member of the Opuntia genus that is found throughout all of the American Southwestern States including Nebraska and even South Dakota and is found across most of Northern Mexico. One of the things that make this particular species so amazing is the adaptability to drastically different environments: it can be found thriving in the driest of lowland deserts to the moist, cold forests of the Rocky Mountains. As a result, there are several variable physical attributes that make identifying this species confusing at best. Springtime flowers are variable from lemon yellow, orange or pink, usually with but sometimes without a reddish center. This one was found growing in the Ajo Mountains in Southern Arizona near the Mexican Border.

  • This tiny daisy grows in many of the hottest, most arid deserts of the American Southwest in sand, gravel and scattered rocks. Easily identified by both it's dimunitative size and choice of habitat, close inspection of the foliage reveals a very wooly, hairy hovering of silvery hairs on the leaves and stem. This was one of many found in an open area in the Mojave Desert in Southern California.

  • Early morning photograph of a native Mojave yucca in its natural habitat on a cool spring morning in Mojave Desert in Southern California. These are often found growing among the Mojave's iconic Joshua trees - another member of the same genus.
    Mojave Yucca
  • Photographed slightly from above, this Mojave yucca in the Mojave desert was historically a very important resource for the Native Americans who lived here. The tough yet pliable fibers in the leaves (needles) after beating them to break them apart were braided together to make rope, sandals, and woven together to make cloth.

  • Early April in the Joshua Tree National Park is a great time for photographing blooming cacti. Some parts of the Mojave contain vast groves of certain species, such as this teddybear cholla, which will seemingly burst into flower all at once, creating a brightly colorful paradise in the middle of the desert.

  • The Great Basin whiptail (Aspidoscelis tigris tigris) is a subspecies of the common western whiptail found in Southeastern California. Found throughout most of the American Southwest, whole populations of western whiptails tend to stay in the same region resulting in great variety of patterns, stripes, and spots based on geographic location across their range. This one was photographed in the Mojave Desert in Joshua Tree National Park.

  • The pencil cholla is easily distinguished from other cholla cacti in the American Southwest by the scale-like arrangement on the stems that is often referred to as a diamond pattern. I thought the yellow coloration on the spines were beautiful, especially backlit like this here in the Mojave Desert in Southern California.

  • The Joshua tree, symbol of the Mojave desert, reaches out into the blue early April sky. One reason it is believed that this iconic yucca is losing habitat, and declining in numbers is in the fossil record of the recent extinction (in geological years) of the Shasta ground sloth, one of the giant sloths that went the way of the mammoths and other American megafauna. Fossilized scat shows the remains of the seeds, leaves and pulp of joshua trees... and was possibly in a loose symbiotic relationship with it as to provide food in return for seed propagation.
    Joshua Tree
  • The Joshua tree is the king of the Mojave desert. Reaching upward to 30'-40' tall, it is also losing habitat quickly. Luckily a few healthy and dense pockets still exist in Southern California such as these in the Joshua Tree National Park.
