Maybe Cordyline australis 'Red Star'? I have a plant that I think is that, but the spelling was wrong on the label. Nothing turned up on a search using the name it was labeled. Here's what I'm growing and think might be Cordyline australis. Mine likes lots of water and doesn't have a large root system for the plant above to be so large. Mine is actually in a smaller container sitting in a rubber tub inside the big one. I had to do something because it didn't take much wind to topple it. I've subsequently covered and packed large pine chips in so it looks planted.
