A true survivor from arid regions, this cactus has evolved remarkable water-storing abilities in its thick, fleshy leaves or stems. Perfect for forgetful waterers or frequent travelers, it actually thrives on neglect. Native to drought-prone habitats, it's adapted to intense sun and little water, making it incredibly low-maintenance. Place it in your sunniest spot and water sparingly, overwatering is the only real way to harm this resilient beauty.
