I recently got this older plant from an obviously very skilled grower in the UK and I'm really excited to grow it from now on. Such a majestic tree it is! I only have small pots to offer at the moment so from any point of view it's better for it to be elevated. And even like this the thickest part of the "trunk" ist still underground.
The leaves are slightly different from those my younger plant has, more nananthus-like. My younger and smaller A. rubrolineata also has thick roots but even though it's raised up as well, modest as it is, it hides them behind its wide leaves.
