It seems like cordyline cultivars are becoming more prevalent. I know I haven't grown it much in the past, but find myself reaching for it more and more when I'm out nursery shopping, probably because it comes in such fun colors. I'm not sure how cold-hardy it is, but will have a chance to find out soon, I'm sure.
Cordyline 'Red Sensation'
Cordyline 'Pink Something-or-other'
