I live in Jupiter, FL. Zone 9. As a travel RN, I was fortunate to have had an assignment on Maui and fell in love with this vine. I know I reside on the border of where this plant will thrive. Do you think I should give it a go? I was told it needs to be planted on the southeast side of my house.
You could grow in a pot and even try it as an indoor plant if temps drop to low.
Sometimes it's fun to take on a challenge! Best of luck.

The black in the branch runs all the way through, on bigger branches it looks triangular. The vines dry to a powdery wood "crumb" which disintegrates if you pinch it between your fingers.
I could not find specific diseases listed but I did find that this vine is very susceptible to root diseases if grown in soggy soil or poorly draining, heavy soil.
There is nothing that will help vines that have died off from this, but you could try amending the soil around the plant.

How big the pot must be to grow it indoors, my floor is made of laminated wood. The place where it will be is 1.5 meters wide x 3 meters long (it is my kitchen) and it has a glass roof. It is a small space inside my apartment that is like a garden with a transparent glass cover. Thanks!
The container sounds big enough, but you must be sure it has adequate light. If there isn't enough natural light, you will need to supplement with artificial light. Here is how to grow the plant:
