Poaceae⚠ InvasiveFountain grass
Cenchrus setaceus
A tufted bunchgrass with arching, wiry leaves and eye-catching purplish to coppery bottlebrush plumes. Widely sold as an ornamental, it is a non-native invasive that escapes landscaping into wildlands, crowding out natives and carrying fire through desert that rarely burned before.
✿ Blooms May – Oct
AmaranthaceaeFourwing saltbush
Atriplex canescens
A gray-green evergreen shrub named for the papery four-winged seeds that clothe the female plants into winter. One of the most salt- and drought-tolerant natives, thriving where little else will.
✿ Blooms Jun – Aug
FagaceaeGambel oak
Quercus gambelii
A deciduous, often thicket-forming oak with lobed leaves that blaze russet and gold in autumn, forming the dense 'oak brush' that carpets foothills and canyon slopes across the Southwest. It anchors soil, feeds wildlife with acorns, and shifts between a shrub and a small gnarled tree depending on site.
✿ Blooms Apr – May
Zygophyllaceae⚠ InvasiveGoathead
Tribulus terrestris
A ground-hugging annual that spreads flat mats of trailing stems with paired, ferny leaves and small yellow flowers. This non-native invasive is notorious for the hard, sharp-horned burrs it drops — spiny seed cases that puncture bike tires, injure bare feet and pet paws, and hitchhike everywhere.

Ponderosa pine
Pinus ponderosa
A stately, long-needled pine whose thick, plated bark smells of vanilla or butterscotch in the sun and glows cinnamon-orange on mature trunks. It defines the open, park-like forests of the Southwest's mid-to-high elevations.
CactaceaeRainbow hedgehog cactus
Echinocereus rigidissimus
A solitary, cylindrical hedgehog cactus whose dense, comb-like spines form alternating bands of pink, white, and rust that spiral up the stem like a rainbow. In late spring it crowns itself with large, silky magenta flowers with paler throats — one of the desert's most photographed miniatures.
✿ Blooms Apr – Jun
Red yucca
Hesperaloe parviflora
A grassy clump of arching, blue-green succulent leaves that sends up tall wands of coral-pink tubular flowers for months, one of the top hummingbird plants in Southwest landscapes. Despite the name it is not a true yucca.
✿ Blooms May – Sep
SalicaceaeRio Grande cottonwood
Populus deltoides wislizeni
The great gallery tree of the bosque — massive, spreading cottonwoods whose golden fall color lines the Rio Grande. A true riparian species that needs a water table or a ditch, not a dry yard.

Datura wrightii
A sprawling, gray-green mound with huge white, trumpet-shaped flowers that open at dusk and perfume the night to attract hawkmoths. Dramatic and beautiful — but every part is dangerously poisonous.
✿ Blooms May – Oct
CactaceaeSaguaro
Carnegiea gigantea
The towering, many-armed giant that defines the Sonoran Desert, its pleated green column crowned in late spring with waxy white flowers. A slow-growing keystone that shelters and feeds desert wildlife for well over a century.
✿ Blooms May – Jun
Tamaricaceae⚠ InvasiveSaltcedar
Tamarix ramosissima
A feathery, gray-green shrub or small tree with tiny scale-like leaves and showy pink to whitish flower plumes. A non-native invasive that forms dense thickets choking Southwest rivers, guzzling groundwater and salting the soil so native cottonwoods and willows can't compete.
✿ Blooms Apr – Sep
Santa-Rita prickly pear
Opuntia santa-rita
A striking upright prickly pear whose round blue-gray pads flush vivid purple to lavender under cold and drought stress. Bright yellow spring flowers against the purple pads make it a prized ornamental of the Sonoran and Chihuahuan borderlands.
✿ Blooms Apr – Jun

A low rosette of narrow blue-green blades that throws a tall spike of creamy bell flowers in early summer, pollinated exclusively by the yucca moth. Common on grassland and mesa across NM.
✿ Blooms May – Jul
CactaceaeTeddy bear cholla
Cylindropuntia bigelovii
A small treelike cholla whose densely silver-spined joints glow when backlit, giving a deceptively soft, fuzzy look. Its detachable segments cling ferociously to anything that brushes them, earning the 'jumping cholla' name.
✿ Blooms Feb – May
CactaceaeTree cholla
Cylindropuntia imbricata
The upright, many-armed cholla that dots NM grasslands, with magenta flowers in early summer and persistent yellow tubercled fruit. Dead stems dry into the hollow 'cholla wood' sold in curio shops.
✿ Blooms May – Jul
AmaranthaceaeWinterfat
Krascheninnikovia lanata
A soft, low, silvery-white shrub whose woolly, star-haired foliage and fluffy seed tufts glow almost luminous in late-season light, blanketing flats and mesas in silver. Its dense winter seed heads give it both its name and its value as cold-season forage.
