Yucca Rostrata - Growth

Hello

I am wondering if anyone can answer my question. I am buying the Yucca Rostrata attached and would like to know from peoples experiences how long from this size will it likely take before growing any trunk?

Thanks

 

Sorry not one I've grown but I would guess a few years, perhaps 5 maybe before you get a trunk of any size.

 

Could be longer than five years, they're one of the slowest. This would be reflected in the price of a trunked specimen

 

Thank you :-)
