Hi welcome

One of our lovely hostesses will probably be by to move your post to a better location where you will get more answers. I am a beginner gardener and am not familiar with any of your plants. Off of the top of my head I would say that if they are tropical and you are in a desert no they would not survive. But like I say I am not familar with your plants at all. I just stopped by to welcome you to the forum.

in las vegas, you get snow. and cold. so your plants won't survive totally outside all year unless you make some provisions for them. what i would do is move them outside to a porch or patio that you can create a "green house" around then in the winter. either that, or cut them back (i do that a lot...) i cut my draceana marginatas back about once every 2 years and plant the cutting. sometimes i give the cutting away, and sometimes i just keep it. they will also survive some amount of "root boundedness" and you can also root prune them.

the palms are a different story. i don't know hwat to tell you about them.
