I don't think the sun would be a problem, but frost will ruin foliage. As fast as they grow with plenty of sun and water, those leaves would easily/quickly be replaced if you did have an occasional problem and occasional damaged tips are OK with you.

Pics of some of mine in the ground here (and a new pic from a couple weeks ago below.) I anticipate any I don't dig up will be killed by winter here, not just frost on some leaves. I would certainly try a few experimental pieces in your location.

I live in Torrance, CA about 4 miles from the coast. All my sans (maybe 30 plants) are in pots (all species, no tri cultivars) outdoors on shelves in front of a south facing wall. They've been there for over 10 years and although some show leaf damage from low temps or improper watering (too much or too little), they do pretty good.

purpleinopp,
Oh how I wish those plants of yours stayed that bright white with green markings. Looks so nice. You grew them well this year.
Solar,
Do you think trifasciata is more frost prone to damage than the others. Interesting thought. Most can take zone 9?? And trifasciata zone 10??

Stush, thanks! But all I did was a dig a hole, insert plants, then do nothing since March. A dozen inches of rain in July? No problem. Last year - no rain all summer? No problem. At least for summer where possible, I recommend it. So easy to dig up, unlike many other plants. Takes seconds to excavate for trades/postage. Putting in a pot for winter, if necessary, would just take a few more.

I live in a hot valley, more like Africa. I have seen them in front of a Bank along a So. faceing cement wall they all seem to look good all year long. Now I am wondering if my spell check is working. Please let me know my feeling will not be hurt. Norma

Norma,
I for one will never tell some one how to spell. With out spell checker I could not last a minuet. Even spell check gets confused with my typing. Thank you very much for posting.
Stush

the plants outside the hotel are replaced, rotated with fresh plants because over the years, they have not maintained their crisp and perfect appearance. I remember thinking that this would have to be done when I first drove past them. MANY plants in the public landscape are replaced when nobody is looking in order to give the appearance of perfection. If you want to grow them to PERFECTION in So CA, you will need to move them around, put them under shade cloth and in general NOT treat them like perennials under the naked sky. I am sure many of them will survive, but if their appearance matters to you, this is a nice place to grow them, but you will not get perfection, from a cosmetic standpoint.

After thought . . . It's not so much that sans like trifasciata don't like water, it's more that they don't like their feet (roots) to stay wet. So planting them in ground that drains pretty quickly should not be an issue.
