@Chlidonias Apparently so, in an interview with the BBC, one of the plant keepers they said it is called 'Nelson' and grew around a coconut.
Here it is; BBC South News
They talk about the Strangler Fig at 7 mins 30 seconds
In any case, that's pretty cool that they have an actual growing Strangler Fig. It looks kind of hacked-up on the left side which is why I was wondering if it was alive (I thought maybe they'd just imported a chopped-down one as a sort of prop).
