this one is not a willow leaf. The one in the background is a nerifolia. I'm not even sold on the kiki answer either.I don't think it is Benjamina. I think it is nerifolia, or narrow leaf.
Thanks I pry still won't know what this is in 5 years- so it's a dealIf it is Kiki, it will develop a trunk with time and should get very dense. Just started work on two, as the nurseries are featuring standards with excellent branching/ leaf density.
Very short standards by the way.
Testing growing in a simple 5 mm builder's gravel mix with aged compost. Say 80 to 20 compost by volume [ shovel fulls.]
Let you know in 5 years or so.
Good Day
