Cute Cactus Facts
Some cacti can live up to 200 years, despite harsh desert conditions & Some types can survive one or two years without water!
Cactus spines are not thorns; they’re highly modified leaves! But yes, even cactus caretakers have been known to call them “thorns” a time or two.

The water a cactus holds is far from clear and pure! It’s thick and sticky, yet still drinkable. So all those western movies about cactus juice saving lives are true!
A cactus appears on Mexico’s national coat of arms, along with an eagle and snake. That’s because Mexico City’s original name translates as “place of the cactus rock.”
