Sedum, an herbaceous perennial succulent, can be found in many areas of the world. It is also very adaptable indoors. Getting the soil right won't do you any good if you plant your cactus in a container without adequate drainage. Succulents are adaptable, and can thrive in all kinds of conditions provided they have enough water and sunlight. Remember that succulents thrive in dry environments and don't need to be exposed to excessive moisture. It's not as difficult to buy succulents online as it was once.
