The Little Barrel

We're in the process of removing lawn and other plants to reduce our water consumption.
In one corner of the garden there used to be a very large bush of some kind which used a lot of water and made a mess.
This has been replaced by this little barrel cactus. It measures about 2 feet / 60 cm across now.
I have been told some day it will be over 6 feet / 2 meters across.
Then it will no longer be a little barrel.
