This does not look like Aloe castilloniae, which has short, recurved leaves and sideways to downward growing stems. More likely a hybrid. I see a bit of
in the mix, maybe. In any case, I would like to propose moving this image to the genus entry.
Aloes (Aloe)
Inviting the contributor and
@ketsui73 to comment in case they know the name for this plant. The hybrids of castilloniae tend to be dominated by castilloniae (especially with regards to leaf shape) so I think it may actually be unrelated (except as a distant cousin).
