Pony Tail Palm
Because of its somewhat palm-like appearence and the bunches of long, thin leaves, Beaucarnea recurvata has come to be called "ponytail palm". However, it's not actually a palm.
The base of the trunk swells dramatically as the plant grows, so bear this in mind when selecting a site. It can be kept in a container for a while, but will break pots and gets very heavy.
The ponytail palm was covered in more detail in the 26-02-2021 edition of Get Results Gardening. That's a weekly email publication for Australian gardeners, especially those in the tropical, subtropical and warm temperate regions. If you request a free trial (see calyx.com.au/getresultsgardening.html for instructions) you can also ask for a copy of the 20-03-2020 edition to be sent as well if you want to read that article (Australian residents only, please).
