   1, Arizona (USA)

   is in the south and southwest of Arizona, where large tracts of cactus have become a spectacular sight. The mountains of the north of the United States are covered with lush coniferous forests, while the south is a flat desert. There, the giant pillar, which is almost unskilled but can be up to 18 meters high, is probably the favorite species of cactus for photography lovers. Texas in the United States also has a considerable number of cacti. Many of them are favored by cactus lovers. But mainly small species that are not conspicuous in the wild.

   2, northern Mexico

The vast expanse of land    stretches from San Luis Podowest to Gora Villa and Chihuahua seems barren. The broad plain was covered with bare rocks, which at first glance would be thought of as barren land. But if you look closely, you will find that there are many small cacti, mainly deer antlers, on the uncultivated hillsides. The white woolly papillae species are scattered sporadically in the areas with strong light, while the green, short-spiny plants of the same genus are mostly green in the areas with less intense sunlight.

   3, Southern Mexico

   southern Mexico, roughly from the city of San Luis Bodo to Oaxaca is a plateau area of about 2000 meters above sea level, surrounded by mountains and several volcanoes more than 5000 meters above sea level. Therefore, there are great differences in soil quality and climate types in this not-so-vast land: the main vegetation in the mountain area is coniferous forest, the representative vegetation in the foothills is oak forest, there are epiphytes in the forest, and the cactus is the most eye-catching plant in the plateau. There are Baiyun Pavilion, which is up to 10 meters high and resembles a new organ sound tube, a simple wide thorn ball that is more than one person high, and a variety of cactus and mastoid plants.

   4, Baja California

   except for the heavily desertified areas in the north, Baja California has slightly more rainfall than Mexico. Farther south, it rains more in summer and is almost frost-free throughout the year, so this area is rich in large, multi-tech columnar cactus, such as the military wheel column of the genus Ferris, which lives with native chlamys, with stems up to 15 meters high and 1 meters in diameter. Also impressive are the dangling Dang Ma Pavilion, creeping deer shaped like giant caterpillars, and the large barrel-shaped Forbidden City. In addition, many cactus plants, especially the 4-meter-high Koula cactus, are also very eye-catching, their stem nodes are very easy to fall off and take root as soon as they fall to the ground, and other succulent plants, especially tequila, are also abundant here. Among the small cacti, the succulent mastoid and many pineapple balls attract more attention.

   5, Peru

   the Andes of South America can be roughly divided into three cactus-rich areas. The first is the plateau between the Peruvian mountains facing the Pacific Ocean in the north and the plateau between latitudes 4 °- 18 °S, and the second is the deviation between northern and central Chile, which is separated by the extremely barren Atacama Desert between latitudes 18 °- 30 °S. in addition, many cacti grow in the basins between the Andes.

   6, North and Central Chile

   serious desertification in parts of northern Chile, precipitation and fog can not meet the water needs of large cacti, but the gray-white dragon claw jade and gray-brown Chilean globules adapt to the stony soil of the region, and columnar species grow on the foggy bank slopes, such as Caragana and Caragana. The climate here is characterized by little rainfall but foggy (fog weakens ultraviolet light). Because this climate is difficult to imitate, the cactus native to Chile is not easy to cultivate.

   7, the Andes Plateau region of northwestern Bolivia and Argentina

   except Mexico, the plateau region of the Andes is the region with the most abundant cactus species. On the slopes and valleys east of the Andes, there are many tall columnar cacti growing above the growth belts of tropical rain forests and deciduous forests, reminiscent of the scenery of Mexico. In almost barren open areas, there are more small globular species, such as Echinopsis, Lobivia, Parodia, Rebutia and Goubaoshan, which are hardy, adaptable and able to withstand the great temperature difference between hot noon and cold nights.

   8, Catingos and Serdo, northeastern Brazil

In the continental climate zone of northeastern Brazil,    grows a large number of cacti and thorny shrubs in the states of Bahia and Minas. Columnar cactus is an important vegetation here.

   9, Campos, southern Brazil

The precipitation of    gradually increases from northeast to south. Sparse forests become the representative vegetation in the south, while cacti are rare, but the Mato Grosso, Rio Grande do Sul and Glenenko regions are rich in cacti, where it rains in summer and dries up in the interior with the advent of winter. this climate is still atypical for succulent plants, so cacti grow mainly in a special soil environment.

   10. Lowland plains of northern Uruguay and Argentina

   in the south of Brazil, Uruguay and northern Argentina, sparse forests have been replaced by grasslands (but the area is now almost entirely arable). The number of cacti here is almost negligible, but most of the popular cactus and naked calyx species come from this region, but most of them grow on the edges of grasslands, in hilly areas, or at the foot of the western slopes of the Andes, in particular, these species usually prefer semi-shady wells and require more water than other species.

   11, Tropical South of Mexico and Central America

   epiphytic cacti need a completely different climate: they live in tropical jungles, and even in places with high rainfall, epiphytes do not absorb much water, so cacti become an important species of American epiphytes.

   12. Tropical woodland of eastern Brazil

Another area where epiphytic cactus is dense in    is the pristine rain forest along Brazil's Atlantic coast, roughly around Rio de Janeiro and Sao Paulo. Unfortunately, only a small number of primitive rain plants are preserved in the mountains, and the main cactus species in this area are cactus and pseudopanthus.
