I totally agree. The deep green color is so beautiful and unique and the droopy frond leaflets are probably what I find most beautiful. And when they are mature, the varying thickness of the trunk adds such a tropical vibe!
As for my Livistona up in NYC, I cover it with a garbage bin and some C-9 christmas lights. It seems like temperatures below 20F will burn all the fronds. There have been some years there's a bit of green left on it. This year it looked totally dead. I really did not expect it to come back, but it is full again!
But it has not grown much since I planted it! Here it was back in 2010, it's first year in the ground...
Sorry I don't have a more recent pic on my Imgur and it's a pain to upload one, so here is a link to the post where I talk about protecting it! I've had it for 7 years now and every season it starts off with at least 50% leaf burn, but it happily returns and looks as nice as if it was greenhouse grown. It does take a while to look good again though.
