The Fan Aloe

This magnificent Fan Aloe (Aloe plicatelis) is flowering in a garden in Muizenberg. Although it is a true fynbos species - occurring only on Table Mountain sandstone soils, in fynbos areas - it is not native to the Cape Peninsula. Which means this one was planted.

I wonder who planted it, and when?
Judging by the size (height: 2.5m), thick woody trunk and slow growth rate of this species, my guess is that it could be 50 to 70 years old. A real grande dame...
