Tamaulipan matorral

Tamaulipan matorral
The Tamaulipan matorral is a desert shrubland ecoregion of northeastern Mexico, spanning the states of Tamaulipas and Nuevo Leon along the eastern slopes of the Sierra Madre Oriental, in low valleys and plateaus between those mountains and the Gulf Coastal Plain. Its vegetation is dominated by woody shrubs, small trees, cacti, and succulents such as mesquite, prickly pear, Spanish dagger, and cenizo, with oaks and madrone at higher elevations. The climate is arid to semiarid subtropical, with piedmont scrub receiving roughly 450-900 mm of annual rainfall. Sitting in a transition between the Nearctic and Neotropic realms, it is a global priority for succulent conservation and a hotspot of mint-family evolution, yet is critically endangered with only about 6% protected.

Nature Imperiled (Dinerstein NNH 4)
Use this as the broad planting pattern for the region: Arid and semi-arid lands where low, erratic rainfall and high evaporation limit vegetation to drought-adapted shrubs, succulents, and sparse grasses. Day-to-night temperature swings are large, and life is finely tuned to water scarcity. For garden decisions, pair that context with the plant list below, then narrow by your site's light, water, soil, and mature-size constraints.

Salvia guaranitica
Anise-scented sage
Anise-scented sage is a tall, upright perennial in the mint family (Lamiaceae), native to Brazil, Paraguay, Uruguay, and Argentina. NC State Extension and Missouri Botanical Garden PlantFinder describe a bushy, square-stemmed plant 2 to 5 feet tall and wide that carries spikes of deep blue, two-lipped flowers with purple-blue calyxes from July into fall; NC State calls it a reliable nectar source for hummingbirds and butterflies, and notes that carpenter bees rob its nectar by biting a hole in the floral tube. The 'anise-scented' name is only partly earned: Wikipedia describes 'an anise scent when crushed,' but Missouri Botanical Garden PlantFinder says the bruised foliage has a very mild aroma with 'very little if any anise scent.' It spreads by tuberous roots that let it reproduce vegetatively (NC State Extension), so it fills a space rather than staying in a tidy clump. It is winter hardy only to about USDA zone 8a: farther north, grow it as an annual or overwinter cuttings indoors, though NC State notes the 'Black and Blue' cultivar is hardier and will survive milder zone 7 winters if well mulched. Neither NC State nor Missouri Botanical Garden documents an edible use or a toxicity hazard. NC State records, as ethnobotanical history, that the Guarani people of Brazil used it as a sedative; that is not a recommendation to take it, so treat it as a non-food ornamental. It has also naturalized outside South America (Wikipedia records it in New Zealand and Chile), so where winters are mild enough for it to persist outdoors, check your local weed or invasive-plant list before planting it.

Achiote (Bixa orellana): pale pink flowers and clusters of red, bristly seed capsules among broad green leaves of a lipstick tree on a spice farm on Zanzibar.
Bixa orellana
Achiote
Achiote, also sold as annatto or lipstick tree, is a fast-growing evergreen shrub or small tree native from Mexico through Central America to Colombia, Venezuela, the Guianas, Ecuador, Peru, Bolivia, Brazil, Paraguay, and northern Argentina, and planted across the tropics for its seeds. Clusters of pink or white flowers about 2 inches across, like single wild roses, open at the branch tips and are followed by clusters of red to red-brown capsules covered in soft bristles, which split open to show seeds coated in a waxy red-orange layer. That coating is annatto: the coloring and mild seasoning behind achiote paste and sazón, the yellow-orange of many cheeses, butters, and margarines, and the red body paint and lipstick that gave the plant its English name. In a garden it usually stays 6 to 12 feet tall and wide as a specimen or informal hedge, though as a tree it can reach 20 to 30 feet. It is frost-tender and needs a frost-free climate: it is hardy outdoors in USDA zones 10a-12b and grown elsewhere in a large container or conservatory that comes indoors before frost. Outside its native range it has naturalized on many Pacific islands, sparingly so in Hawaii, and in the Galapagos, where the Charles Darwin Foundation rates it potentially invasive.

Acalypha wilkesiana
Copperleaf
Copperleaf (also called Jacob's coat or fire dragon plant) is a fast-growing tropical evergreen shrub from Fiji and neighboring islands of the South Pacific (Vanuatu, the Solomon Islands, the Bismarck Archipelago, and Tuvalu), grown almost everywhere else for its foliage. The species has large, broad, coarsely toothed leaves mottled coppery green and red; the pink, cream, gold, and ebony-purple leaf patterns sold in the trade belong to named cultivars such as 'Blackie', 'Bronze Pink', 'Java White', and 'Tricolor', not to the plain species described here. The flowers are tiny and insignificant, carried in slender catkin-like spikes on the same plant: long hanging male spikes and short female spikes that are often hidden among the leaves. It is frost-tender and reliably hardy only in USDA zones 10a-11b; everywhere colder it is grown as a warm-season annual or as a container plant brought indoors for winter. In a frost-free landscape it can reach 8 to 12 feet tall and 6 to 8 feet wide, though as a container or bedding plant it usually stays around 3 to 4 feet. Treat it as an irritant: the RHS lists the cultivar 'Obovata' as a skin and eye irritant and harmful if eaten. It is listed as introduced in Florida, Hawaii, and Puerto Rico, but UF/IFAS does not consider it a problem species in Florida at this time.

Baja California desert
The Baja California desert spans the western Baja California Peninsula in Mexico, across both Baja California and Baja California Sur states, bounded by the Pacific to the west and the Peninsular Ranges to the east. Its xeric shrublands hold close to 500 vascular plant species, including the endemic boojum tree (Fouquieria columnaris), creosote bush, and many cacti, with roughly 23% of plant species endemic. The climate is dry and mostly subtropical; the Pacific Ocean adds humidity and moderates temperatures, while the driest interior areas receive less than 50 mm of rain a year. About 60% of the ecoregion lies in protected areas, including Mexico's El Vizcaíno Biosphere Reserve.

Central Mexican matorral
The Central Mexican matorral is a semi-arid shrubland ecoregion of roughly 59,400 sq km on the southern Mexican Plateau, encompassing the Valley of Mexico and Mexico City, North America's largest metropolis. This relatively flat desert reaches elevations up to about 2,000 m and is ringed and dotted by mountain ranges. Its climate is subtropical and semi-arid, with warm summers, occasional summer rains, and cool winters; average annual precipitation is under 500 mm. The characteristic vegetation is dry matorral dominated by cacti, agaves, and shrubs such as lechuguilla and acacias, with the golden barrel cactus (Echinocactus grusonii) as a flagship species. Geographic isolation drives exceptionally high endemism, but the ecoregion is classified critical/endangered, with little protected habitat and pressure from agriculture, grazing, urban growth, and illegal cactus collection.

Colorado Plateau shrublands
The Colorado Plateau shrublands stretch across the high desert country of Utah, Colorado, Arizona, and New Mexico, an elevated, northward-tilted saucer largely above 1,525 meters and ringed by higher mountains. Pinyon-juniper woodlands dominate, grading into big sagebrush and semi-desert shrubland at lower elevations and ponderosa pine forest higher up. The climate is arid to semiarid, with cold winters and hot summer days. Carved by the Colorado River and its tributaries, the region holds iconic landscapes such as the Grand Canyon and roughly 300 endemic plant species, yet only about 11% is protected.

Great Basin shrub steppe
The Great Basin shrub steppe spans most of Nevada and much of Utah, with adjoining areas of California and Idaho, bounded by the Sierra Nevada to the west and the Wasatch Mountains to the east. Its landscape is a series of uplifted fault-block mountains separated by intervening basins, vegetated by big sagebrush along with bluebunch wheatgrass, Idaho fescue, and pinyon-juniper woodlands. The climate is extreme and arid: less than 250 mm of annual precipitation, with recorded temperatures at Elko, Nevada ranging from -42°C to +42°C. Roughly 100 internally drained basins hold remnant Pleistocene lakes such as Great Salt Lake and Pyramid Lake. Invasive cheatgrass and the unnaturally frequent fires it fuels are a leading conservation threat.

Gulf of California xeric scrub
The Gulf of California xeric scrub runs down the eastern side of Mexico's Baja California Peninsula along the Gulf of California, from the gulf shore up to the crest of the Sierra de la Giganta and across several gulf islands, covering roughly 23,600 km2. It is a dry, low-mountain landscape (mostly 200-1,000 m) of desert shrubland dominated by creosote bush, white bursage, and ironwood. The climate is arid and subtropical, with some of the lowest precipitation in all of Mexico (under 100 mm). Distinctively, much of the region's biodiversity and high endemism is tied not to the open scrub but to scattered palm oases; roughly half the ecoregion lies within protected areas.
