  • Close-up of the branches of the ocotillo, a somewhat common Southwestern plant found in most of the Sonoran and Chihuahuan Deserts. In the spring, the long, thorny spines sprout small green leaves and brilliantly orange flowers from the mature stems that attract and are pollinated by hummingbirds and carpenter bees. This one was found way out in SE California near the Arizona Border in Imperial County.

  • When looking at the flower of the Himalayan blackberry, it's easy to see that it actually is a member of the rose family. A favorite of bees and loads of other wildlife who love the delicious sweet blackberries that come later in the summer, this highly invasive import which is actually from the Armenia area (not sure where the  Himalayan part of the name comes from)  thrives in the Pacific Northwest and is a major pest for gardeners and forest stewards all over the region. This one was found in the Woodard Bay Conservation Area just outside of Olympia, Washington on a beautiful summer afternoon.
    Himalayan Blackberry Flowers
  • The highly controversial and extremely invasive Himalayan blackberry is might be considered the classic success story if looked at from the the view of this extremely aggressive invasive plant. Why it is called the Himalayan blackberry is a mystery to me, but it originally comes from Armenia and Iran. Introduced to the East Coast of the United States in 1885, it is believed it was confused with a similar European species of blackberry and with the help of local birds who absolutely love the berries, it had reached reached the West Coast of North America. This plant grows fast, easily outcompetes native foliage and is extremely tough to eradicate. On the plus side, this particular blackberry puts out bumper-crops of blackberries every summer that are absolutely delicious. I often see bushes laid out flat on the ground under the weight of all the berries. These were found growing in the Woodard Bay Conservation Area just outside of Olympia, Washington.

  • Common in southeastern Arizona, Baja California and Sonora in Mexico, parts of Southern California, as well as select locations in Utah and Nevada, the buckhorn cholla gets its name from its similarity in appearance to deer antlers. Flowers are quite variable in color - ranging from lemon yellow, fiery orange to a deep scarlet, and are followed later in the season by smooth, plump, mostly spineless, green, purplish, or reddish edible fruits. Like many other cactus species in the Southwest, the mature fruits of the buckhorn cholla drop off long before it blooms during the next season, therefore you will never see one with both fruits and flowers at the same time. This one was photographed in the Puerto Blanco Mountains of Southern Arizona near Sonoyta, Mexico.

  • Close-up view of the teddybear cholla in flower. This common and impressive native cactus of the American Southwest is found Southern California, Nevada and Arizona, as well as most of Northern Mexico. 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.

  • This cactus is native subspecies of the green-flowering hedgehog cactus and is common from mid-to-high elevations, favoring volcanic soils. The cylindrical stem of this cactus may branch to form large colonies. Rusty-red flowers with darker purplish maroon midstripes and greenish-yellow anthers grow from the middle third of the stem and do not open very wide. Found in the United States only in Brewster County in the Big Bend area of Texas, this one was found growing below the Chisos Mountains near the Rio Grande.

  • 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 snowball cactus - also known as the mountains ball cactus or Simpson's hedgehog cactus - is very similar to many of the hedgehog cacti of the American Southwest, except this species is found natively only in the arid sagebrush deserts of Oregon and Washington. Sometimes found growing singly or in pairs, they can also form massive clumps of plants and are unfortunately becoming rare in their native habitat due to plant poaching by collectors, which is unfortunate as they don't take to replanting well. This photo was taken just to the west of Vantage, WA in the rural hills near Whiskey Dick Mountain.

  • The spiny-fruited prickly pear (Opuntia x spinosibacca) is a naturally occurring hybrid between two overlapping Opuntia species (O. aureispina and O. phaeacantha) found in the Big-Bend Region of Texas and is believed to be reproducing with others of the same hybrid in the wild, which is a common way over time we end up with distinct new species. In some circles, it is already being referred to as a unique species: Opuntia spinosibacca. Although they are considered rare in the wild, I happened to find many hundreds of them in bloom like this one spread out in the lowland region north of the Chisos Mountains in Big Bend National Park in West Texas near the Rio Grande.
    Spiny-Fruited Prickly Pear
  • This beautiful thick, cylindrical cactus found here in Big Bend National Park in West Texas is a species with dozens of common names such as: straw-colored hedgehog, pitaya, alicoche, green strawberry hedgehog cactus, etc. It is found natively in the Chihuahuan Desert close to the Rio Grande, specifically in west and south Texas, Dona Ana County in southern New Mexico, as well as in the Mexican states of Chihuahua, Coahuila and Sonora. Recent spring rains have caused these plants to swell up with stored rainwater.
    Cob Cactus
  • The nylon hedgehog cactus (Echinocereus viridiflorus var. cylindricus) is native subspecies of the green-flowering hedgehog cactus, and is found in a narrow band stretching from the Big Bend of Texas and Mexico to southern New Mexico, and is mainly found in the Franklin Mountains near El Paso, Texas. It has distinct creamy orange flowers and shows extreme variability in spine color: white, yellow, brown, reddish, black. Some plants have only short radials while other have a variable number of centrals. This one was photographed in the Big Bend National Park near the Rio Grande.

  • One of the most striking and beautiful of all the "barrel" cacti of the American Southwestern deserts, the claret cup cactus (also known regionally by many names such as the kingcup, queencup, hedgehog cactus, pitaya roja, etc.) has large, showy and brilliantly red flowers that attract and are pollinated by hummingbirds. Unlike most cacti, the flowers of the claret cup stay open at night. Some native American tribes who shared the same habitat would collect these cacti, burn off the sharp spines, and mash them into a pulp with some locally procured sweetener (honey?) and bake them into mini sweet cakes. This one was found and photographed on a beautiful spring day in the Sevilleta National Wildlife Refuge in Central New Mexico.

  • This unusual flattened, short cactus is more common in its range than one might think, but because it barely grows above the ground level and can be as wide as four inches. Easier to find in the spring and summer, it can be difficult to spot in the winter when it is nearly below ground level and may be partially covered in gravel. The little nipple cactus (as well as all other members of its genus) are much more common in Mexico, but this species can be found in the United States in Texas, Colorado, New Mexico, Arizona and Oklahoma. This one was found as it was just about to flower in Big Bend National Park, in the lowlands just north of the Chisos Mountains in Western Texas.
    Little Nipple Cactus
  • Found only within the greater Big Bend Region, this prickly pear can be vibrant green during wet times, or deep magenta during colder months or dry times. Yellow flowers with red centers will bloom from April to July.  This one was photographed<br />

  • This incredible wild and harsh desert near the Mexican town of Sonoyta is deep in the Ajo Mountain range in Southern Pima County, Arizona. Saguaro cacti, gila monsters, rattlesnakes, scorpions, tarantulas, a searing sun are staples of this dangerous part of the Sonoran Desert, and there is a long, deep history among the remnants of the Tohono O'odham Nation who thrived here for centuries, and the ancestral Puebloans who created a vibrant culture here before them.

  • Slightly smaller than other raven species found around the world and about the size of the American crow, this Mexican raven may look like any other raven, but the differences stop there. Most notably, the under-feathers on its neck are pure white. In the dry grasslands of the American Southwest it replaces the common raven (Corvus corax) of the north and breeds in the Southwestern United States, but it is far more common to the south in Mexico where it is found year-round. At northern end of range (eastern Colorado, western Kansas), the Chihuahuan raven is far less common today than in 1800s. I saw this one quite by accident as I was setting up my tent and cooking some dinner on my travels on a small ground fire on top of a hill overlooking Sonoyta, Mexico in Southern Arizona on the US-Mexico border. It got my attention by crowing on top of an almost-flowering saguaro cactus while I was waiting for the water to boil on my camp stove.

  • 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.

  • A rare find! Usually found singly, this trio of young fishhook barrel cacti was found and photographed in the Alamo Canyon, deep in the Ajo Mountains of Southern Pima County, Arizona near the Mexican border.  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. 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.

  • 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.

  • This natural hybrid (Opuntia engelmannii x phaecantha) of two common and local prickly pear cacti - the Engelmann's Prickly Pear (Opuntia engelmannii) and the brown-spined prickly pear (Opuntia phaecantha),  shows characteristics of both and have resulted in a large, mature beautiful cactus growing at some elevation in the Ajo Mountains in Southern Arizona. Since so many of our native members of the Opuntia genus are so closely related and have overlapping natural ranges, hybridization is common among many species, and is the source of much confusion and frustration for biologist and naturalist alike! This particular plant has the beautiful silvery white spines and flower petal shape of O. engelmannii and the flower coloration and growth pattern of O. phaecantha.
    Natural Prickly Pear Hybrid
  • 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.
    Brown-Spined Prickly Pear
  • This beautiful thick, cylindrical cactus found here in Big Bend National Park in West Texas is a species with dozens of common names such as: straw-colored hedgehog, pitaya, alicoche, green strawberry hedgehog cactus, etc. It is found natively in the Chihuahuan Desert close to the Rio Grande, specifically in west and south Texas, Dona Ana County in southern New Mexico, as well as in the Mexican states of Chihuahua, Coahuila and Sonora. Recent spring rains have caused these plants to swell up with stored rainwater.

  • The cane cholla is a very common native cactus species found across much of Arizona and New Mexico in the United States, and Chihuahua and Sonora in Mexico. It prefers sandy to loamy soils at lower elevations, and has a lot of variety when it comes to flower color, and they are almost always very bright in color: yellow, pink, red, orange, etc. These were found just north of the Organ Pipe Cactus National Monument near Ajo, Arizona growing naturally in the Sonoran Desert on a bright, sunny spring morning near the Mexican border.
    Cane Cholla
  • This beautiful, long and curve-spined cactus is a small member of the barrel cactus family and is primarily found in the central Chihuahuan Desert near the Rio Grande. Barely reaching a height of twelve inches, this attractive and colorful cactus will produce large three-inch yellow flowers in the springtime. This three-inch beauty was found and photographed below the Chisos Mountains in Brewster County, Texas.

  • This fantastically beautiful and very long-spined cactus found in the Chihuahuan Desert of Texas and Arizona in the United States, and in the Mexican states of Coahuila, Chihuahua, and Nuevo León. It gets its species name (stramineus - which means made of straw) from the way these thick, brittle spines resemble dried straw. Clumps of 100 or more stems are not uncommon, and when they are in flower, it is one of the most spectacular of all of the Chihuahuan cacti! This one was photographed in Western Texas in Big Bend National Park.

  • Also known as the purple prickly pear, this incredibly beautiful Mexican Opuntia cactus develops fantastic purple pads that perfectly compliment the bright yellow (sometimes red) flowers. Native to Northern Mexico from Baja California to the Chihuahuan Desert, its American range extends only into Pima County in Southern Arizona where these were found in peak bloom and photographed just outside of the park borders of the Organ Pipe Cactus National Monument.

  • 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 lit this here in the Mojave Desert in Southern California.

  • The snowball cactus - also known as the mountains ball cactus or Simpson's hedgehog cactus - is very similar to many of the hedgehog cacti of the American Southwest, except this species is found natively only in the arid sagebrush deserts of Oregon and Washington. Sometimes found growing singly or in pairs, they can also form massive clumps of plants and are unfortunately becoming rare in their native habitat due to plant poaching by collectors, which is unfortunate as they don't take to replanting well. This photo was taken just to the west of Vantage, WA in the rural hills near Whiskey Dick Mountain.

  • Common in southeastern Arizona, Baja California and Sonora in Mexico, parts of Southern California, as well as select locations in Utah and Nevada, the buckhorn cholla gets its name from its similarity in appearance to deer antlers. Flowers are quite variable in color - ranging from lemon yellow, fiery orange to a deep scarlet, and are followed later in the season by smooth, plump, mostly spineless, green, purplish, or reddish edible fruits. Like many other cactus species in the Southwest, the mature fruits of the buckhorn cholla drop off long before it blooms during the next season, therefore you will never see one with both fruits and flowers at the same time. This one with deep red and yellow flowers was found and photographed in the Alamo Canyon, deep in the Ajo Mountains of Southern Pima County, Arizona near the Mexican border.

  • 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.

  • The spiny-fruited prickly pear (Opuntia x spinosibacca) is a naturally occurring hybrid between two overlapping Opuntia species (O. aureispina and O. phaeacantha) found in the Big-Bend Region of Texas and is believed to be reproducing with others of the same hybrid in the wild, which is a common way over time we end up with distinct new species. In some circles, it is already being referred to as a unique species: Opuntia spinosibacca. Although they are considered rare in the wild, I happened to find many hundreds of them in bloom like this one spread out in the lowland region north of the Chisos Mountains in Big Bend National Park in West Texas near the Rio Grande.

  • This natural hybrid (Opuntia engelmannii x phaecantha) of two common and local prickly pear cacti - the Engelmann's Prickly Pear (Opuntia engelmannii) and the brown-spined prickly pear (Opuntia phaecantha),  shows characteristics of both and have resulted in a large, mature beautiful cactus growing at some elevation in the Ajo Mountains in Southern Arizona. Since so many of our native members of the Opuntia genus are so closely related and have overlapping natural ranges, hybridization is common among many species, and is the source of much confusion and frustration for biologist and naturalist alike! This particular plant has the beautiful silvery white spines and flower petal shape of O. engelmannii and the flower coloration and growth pattern of O. phaecantha.

  • 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 cactus is native subspecies of the green-flowering hedgehog cactus and is common from mid-to-high elevations, favoring volcanic soils. The cylindrical stem of this cactus may branch to form large colonies. Rusty-red flowers with darker purplish maroon midstripes and greenish-yellow anthers grow from the middle third of the stem and do not open very wide. Found in the United States only in Brewster County in the Big Bend area of Texas, these were found growing below the Chisos Mountains near the Rio Grande.

  • The cane cholla is a very common native cactus species found across much of Arizona and New Mexico in the United States, and Chihuahua and Sonora in Mexico. It prefers sandy to loamy soils at lower elevations, and has a lot of variety when it comes to flower color, and they are almost always very bright in color: yellow, pink, red, orange, etc. These were found just north of the Organ Pipe Cactus National Monument near Ajo, Arizona growing naturally in the Sonoran Desert on a bright, sunny spring morning near the Mexican border.

  • One of the most striking and beautiful of all the "barrel" cacti of the American Southwestern deserts, the claret cup cactus (also known regionally by many names such as the kingcup, queencup, hedgehog cactus, pitaya roja, etc.) has large, showy and brilliantly red flowers that attract and are pollinated by hummingbirds. Unlike most cacti, the flowers of the claret cup stay open at night. Some native American tribes who shared the same habitat would collect these cacti, burn off the sharp spines, and mash them into a pulp with some locally procured sweetener (honey?) and bake them into mini sweet cakes. This one was found and photographed on a beautiful spring day in the Guadalupe Mountains National Park in Northwestern Texas.

  • This unusual flattened, short cactus is more common in its range than one might think, but because it barely grows above the ground level and can be as wide as four inches. Easier to find in the spring and summer, it can be difficult to spot in the winter when it is nearly below ground level and may be partially covered in gravel. The little nipple cactus (as well as all other members of its genus) are much more common in Mexico, but this species can be found in the United States in Texas, Colorado, New Mexico, Arizona and Oklahoma. This one was found and  photographed in the Chisos Mountains in Texas' Big Bend.

  • This fantastically beautiful and very long-spined cactus found in the Chihuahuan Desert of Texas and Arizona in the United States, and in the Mexican states of Coahuila, Chihuahua, and Nuevo León. It gets its species name (stramineus - which means made of straw) from the way these thick, brittle spines resemble dried straw. Clumps of 100 or more stems are not uncommon, and when they are in flower, it is one of the most spectacular of all of the Chihuahuan cacti! This one was photographed in Western Texas in Big Bend National Park.
