While they generally specialize in collecting cacti, they can also include other desert plants such as sabla, agaves or Crassulaceae, although this would better be termed "xeriscaping".
Cacti are succulent plants native to the American continent, typical of arid environments.
[1] Cactariums also tend to host plants from other botanical families, native to the desert regions of the world.
Popularity of these plants constantly grew, which was also facilitated by the biological characteristics of many cacti – tolerance of infrequent watering[4] and dry air (the latter is essential for room culture), and easy vegetative reproduction.
[5] In botanical gardens of many European countries as well as in private greenhouses, significant collections have been accumulated.
