Also known as the bunny ear cactus, this low-growing cactus originates from Northern Mexico but is now a common piece of living décor in many homes across the world. It is called the bunny ear cactus because it has no central stem but is instead composed of many different oval shaped pads. They greatly resemble bunny ears or the ears of a certain cartoon mouse. It is also sometimes called the polka-dot cactus.

Caput medusae roughly translates to “head of Medusa.” If you’re familiar with Greek lore, this is the woman cursed by Aphrodite to live with snakes on her head for hair. The Medusa’s head plant, as it is also known, got this name because of its many tubular stems that grow and curve in different directions resembling snakes. It is tough to grow this plant inside, but if you can manage it is unique and rewarding.

The Christmas cactus is as unique as it is beautiful. It is a hanging cactus that produces very bright and vivid flowers that may be red, yellow, pink, or orange. They tend to grow hanging from trees in the wild in areas with high humidity but can survive perfectly well hanging indoors. The flowers usually grow horizontally from the plant and the top side of the flower grows differently from the bottom side.
