Ti plants are really popular, but they are treated more as perennials than as shrubs. Mine are sprouting back from the ground except where a few canes survived, but they'll at least get leaf burn most winters.
Crotons are marginal. My development planted them this fall expecting them to live for many years but they were toast a few days into January.
The BOP all look awful. I covered mine and put lights around it so it looks green and healthy, but the others suffered at least some dieback. I've seen both white and orange BOP for sale so they are pretty popular.
That's such a good point about up north. It's impossible to tell whether it was the duration of cold or the cold itself that does plants in. In Florida the duration is definitely what kills. My papaya survived temperatures in the mid 20s for 2 nights but even though the future freezes weren't as severe, it eventually lost it's will to keep on fighting.
