Thanks for the information about the scientific name change. I can now better search for the right plant when I talk to nurserys.
I've talked to Aloha Tropicals but they sell small plants and I'd like to get a large mature one. They offered me an over potted 7' plant, but they want $250 for it!
It's easy to find Draceanas here - they sell them at department/chain stores. But Cordylines are hard to find. I don't know why.
I'm asking all my friends who have relatives in Hawaii if they can get get some plants for me. I know I can't get them thru agricultural inspection, but I would try dehydrating the root into chips and ship them thru as a snack.
