I always loved cactus:)
Wikipedia says: "A cactus is a member of the plant family Cactaceae, a family comprising ca 127 genera with some 1750 known species."
One of the best with the cactus you do not need to water very often. "Many live in extremely dry environments, even being found in the Atacama Desert, one of the driest places on earth. Cacti show many adaptations to conserve water."
There is something special in them and you can build a really cute cactus corner in your room. They look great in the paper bag,
in the old chinas,
even in the cactus patterned flower pots
If you have a lot, put into red ceramic pots and you can organized like this:
Of course I collected many more at my Pinterest Bord.
Have a great day!
