  • 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.

  • Engelmann's prickly pear is one of the most (if not the most) widespread of the prickly pear cacti. It is found in all of the American Southwestern States (except Colorado) and can even be found as far east as Louisiana, Mississippi and Missouri and is widespread throughout much of Mexico. Oddly enough , it has become an invasive species in Kenya! The sweet, juicy fruits are a traditional and still very important food source wildlife an for many tribes and nations of the Native Americans and is commonly used in Latin American cuisine.

  • The brittle prickly pear is likely the most widespread cactus in North America. It's range includes the five western Canadian provinces, all of the western American states, and continues south well into Mexico. Because it can be found close to the Arctic Circle, it is also the most northerly cactus in North America. This one was found in flower growing near the Pawnee Buttes in northeastern Colorado.

  • As far as foliage goes, it's hard to beat the beautifully variegated, spiky leaves of the Mexican prickly poppy. As in most wild poppies, it has and intensely colorful bright flower - in this case yellow. Native to Mexico and spreading northward into the central and eastern United States, it has now been found growing in the wild in parts of Ontario and Manitoba where the soil is dry and there is plenty of sunlight! This one was found growing by the banks of the Rio Grande on the US-Mexico border near Alamo, Texas.

  • 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.

  • Common in lower elevations of western/southwestern Texas and much of Mexico's Chihuahuan Desert, this is the only native prickly pear in the region without long spines. Instead, brown hair-like glochids grow in the areoles, which if touched, can be quite painful and difficult to remove. This one was  photographed just north and below the Chisos Mountains in Big Bend National Park in Brewster County, Texas.

  • This great find in a purplish prickly pear cactus flower (Opuntia azurea) in Big Bend National Park in West Texas was an exciting one for me. This bee assassin bug is a clever hunter of bees and other pollinating insects found throughout much of North America. It is most often found inside flowers waiting to stab the unsuspecting insect attracted to the flower's sweet nectar with its sharp proboscis, where it will literally drink its prey dry. Even though this one is covered in pollen, you can still see the warning colors of black and red (aposematic coloration) warning birds and other predators that this bug is not safe to eat or hunt.

  • Close-up flowers of the unique flowers of the cochineal nopal cactus. This incredibly beautiful member of the prickly pear cactus family is endemic to Mexico and has moved across the world by plant enthusiasts and collectors due to its beauty and hardiness. With its stunningly beautiful, cone-shaped bright pink flowers to its relative lack of spines, this tree-like beauty can reach a height of 12-13 feel (4 meters) and the ripe red fruits and cactus pads are edible and delicious! This one was found growing in the Lower Rio Grande Valley in South Texas near Weslaco in Hidalgo County.

  • This young(er) teddybear cholla in Joshua Tree National Park is still mostly covered with fresh spines, all pale, dense, and waiting for a passerby to touch it, enabling a piece to be broken off and carried off to start another plant as soon as it touched the ground. I was unfortunate enough to have a piece stuck to my bare calf, then had my hand stuck to it as I tried to pull it off of me. It was shockingly painful, much more so than any other California cactus I happened to get pricked by.

  • Although this pricklypoppy is not colored red, the flowers of this South Texas native ranges from dark purple to red, bright pink, fuchsia, light pink to pure white. This one was found in a massive disturbed field with several hundred others in Harlingen, Texas in the Rio Grande Valley.

  • This particularly spiky fishhook cactus (also known as a barrel cactus) is common in the Four Corners region where Arizona, Colorado, New Mexico, and Utah meet. What is interesting about this cactus is that it is a xerophyte - which means it is extremely tough in extreme environments, and can withstand long periods of time with little to no water in the blistering summer heat of the high desert in summer, and the deep freeze of winter. If you look closely, you can see where a scorpion has dug a burrow under this one, high on the plateau north of Moab, Utah.

  • 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.

  • Also commonly called the diamond or branched pencil cholla, this hardy tree-like cactus is native to the Mojave and Sonoran Deserts of the Southwestern United States, California, and Northwestern Mexico, and to Baja California and its San Benito Islands. Uncommon in its range compared to other cholla species, the pencil cholla is usually found in well-drained sandy, gravelly, and rocky soils on flats, bajadas, and moderate slopes into the lower mountains in the Lower Sonoran (Creosote-Bursage Flats) and Upper Sonoran (Mojave Desert Scrub) habitats. Easily identified by the smooth surface of the stems with a distinct diamond-shaped pattern, each scale-like flat tubercle sprouts a viciously long, 2-inch golden-tipped silvery-white spine on the youngest and newest growth. This one was found growing along the side of a dried-out arroyo in a nameless canyon in Southern California's Anza-Borrego Desert in San Diego County.

  • 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.

  • 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.

  • 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.
