Echinopsis

Arkham’s Botanical stocks a number of cacti species of the Trichocereus genus, which more properly has now been folded into the Echinopsis family by botanists. For example, Trichocereus pachanoi is now officially known as Echinopsis pachanoi, etc. However, like many Trichocereus fans, we still prefer the old naming conventions!

Echinopsis is a large genus of cacti native to South America, comprising 128 species ranging from large treelike to small globose cactus types. Native to Argentina, Chile, Bolivia, Peru, Brazil, Ecuador, Paraguay and Uruguay, its species grow either in sandy or gravelly soil or in rock crevices on the sides of hills.
