When it comes to houseplants, there's nothing quite as quirky as a cactus – but the fishbone cactus (or Disocactus anguliger) wins the prize for the quirkiest houseplant of all. Also known as a zigzag cactus or a ric rac cactus, this isn't your typical prickly plant; in fact, it doesn't have any spines at all.
Instead, it boasts glossy foliage that starts out as narrow green stems before forming uniquely wavy nodes (which, as you might expect, eventually create a delightful zigzag pattern).
