I recently purchased a beautiful Indoor Cactus (as the tag on the home depot sticker refers to it) and I do not know what kind of cactus it is, and therefore am having trouble finding out how to take care of it.It does say cactaceae on the tag also. I have never owned a cactus before.The one I chose is a cactus that does not have any thorns or prickers (I'm not even sure what they're called!), and currently does not have any flowers. I don't know if it ever does. The leaves look like the cartoon charachter SHREK's ears.he one I chose is a cactus that does not have any thorns or prickers (I'm not even sure what they're called!), and currently does not have any flowers.
