hi,sorry,it dies at 50!
aloha tropicals got me one last year,but ,like it said,died at 50
you could bring it indoors for the winter,as they are quite managable shrubs

I live in central Florida and grow 3 varieties. They all spent the winter in the garden. I just cover them with sheets when a frost is predicted. They do go dormant in the winter and drop their leaves. I purchased all of mine at the HD.

I have two varieties, and although my climate is much different than yours, I can guarentee you they do not die at 50. The all white variety (dona aurora I believe) did not tolerate even my winters. The other varieties have been down to 29 or 30 degrees a few times. The cold extremes did sometimes kill the newer more tender stems, bur that is only a minor setback. I cut mine way back every spring anyway. In my climate, they are easy to care for, and look great a good portion of the year.

They may not actually die at 50F, but they do not like typical California night temps in the 50'sF for months on end. This is an indoor/outdoor plant for southern California, and they prefer it warm all year round. They will do okay in southern Florida because their winter weather is so short, and it usually warms up quite abit during the day. I don't think you will find anyone anywhere in southern California that has this growing year round outdoors.
