It's Alocasia amazonica - it grows from a rhizome or corm, and is frost tender. It gets very large during the growing season- usually started off in spring,then grown outdoors during summer, and then stored as a rhizome over winter, in much the same way as dahlias or cannas. Can be difficult as a houseplant, more information on that here

I was planning to get my eldest girl one for when they get their new house. however it is toxic to cats, dogs and horses. as they have a puss that will be no-no.

Thank you 😊

I have one of these, now 7/8/9 years old. The leaves have got smaller as it got older.
I had no idea it was toxic.
