Cactus

1749 out of 1750 species of cacti are native to only The Americas, ranging from Patagonia in the south to parts of western Canada in the north. The only exception is the Rhipsalis baccifera, which also grows in Africa and Sri Lanka. Not a single cactus grows in the Sahara.

The fruit is fleshy and often edible, as in the case of the prickly pear, which was used for a variety of purposes by the Aztecs.

The Indian fig cactus has long been an important source of food. Both the fruit and pads are eaten, the former often under the Spanish name tuna, the latter under the name nopal. The nopal industry in Mexico was said to be worth US$480 million as of March 2026

Cactus water is the clear liquid that is found inside of cacti. It is a good source of electrolytes and minerals, but it is also very acidic. The acidity of cactus water is caused by the presence of organic acids, such as malic acid and oxalic acid. Contrary to their portrayal in movies and TV shows, drinking cactus water is unsafe. The liquid produced by cacti is highly acidic and will cause vomiting, further dehydration, and in some cases temporary paralysis.

The former UK Deputy prime minister Nick Clegg was given community service as a 16-year-old student in Munich after setting fire to rare cacti owned by Germany’s foremost collector in what he called a ‘drunken prank’.

The saguaro is the largest cactus native to the United States. It grows 10 to 52 feet tall on average, and the tallest saguaro ever recorded — an armless specimen in Cave Creek, Arizona — measured an astonishing 78 feet before it was toppled by a windstorm in 1986. Currently, the largest known living saguaro stands in Maricopa County, Arizona, measuring 45 feet 3 inches and estimated to be around 200 years old.
