Furcraea foetida 'Mediopicta' is a succulent and originates from Central America. So it’s not from Mauritius and it’s not hemp. Neither is it from Bali and it’s not really an agave although the leaves are somewhat similar.
They are related to the Agaves (cousins) and they look like they belong in Balinese-type gardens, plus Balinese agave is much easier to pronounce than it's real name.
I couldn’t find any connection with Mauritius but the leaves of Furcraea foetida can apparently produce sisal (twine) somewhat similar to hemp twine.
Whatever you call it, this is a spectacular plant. I know it enjoys our sub-tropical climate, but with a little research I found it‘s also recommended for desert gardens.
It will tolerate heat. It’s frost hardy to -7C (according to the experts) and it’s not fussy whether it gets a little or a lot of water. Nothing seems to worry it. There are no spikes or barbs like some agaves. It’s fast growing and each year or so produces one or two pups. We started with one and now have three. - My kind of plant.
But (there's always a but) you will need a lot of space. They will grow to about 3m diameter.
This one is in our local botanical garden and towers above me.
