You may get a better answer on the Hawaii forum.

It may be not what LEAVES Hawaii, but what state you are going to enter, and their phytosanitary laws. For California, it has to either have no dirt attached to the roots (if any) or be grown in accordance with strict phytosanitary rules where the plant in question is kept seperate from other plants that might have bugs or disease, and I THINK it has to be inspected regularly at said nursery before it's clear to enter California.
There's a reason for this, some years ago, 5 maybe, I saw on the news that some bug was proliferating in Florida and a few months after that, I won a plant on eBay, from Florida and it arrived with some of those bugs, I freaked out and went and bought some strong pesticide and separated it... I can just see being blamed for an outbreak of that bug, whatever it was!
