Sansevieria trifasciata outside in SoCal?
I have seen this plant (also called snake plant) used indoors in bright light, but I noticed that the Ritz Carlton in downtown Los Angeles had these outside in a planter next to a south-facing wall. They create a very striking effect when planted en masse.
I have a difficult spot in my yard under a sycamore tree that gets full sun in winter when the tree loses it leaves and almost total shade (bright indirect light) the rest of the year. This spot is also fairly dry even though I have irrigation, because the tree roots soak up all the moisture.
The only plants I have been able to grow successfully in this spot are some types of azaleas, clivia, daylilies, agapanthus, and coleus (as an annual). Clivia in particular is well-suited.
It would be great if I could use Sansevieria trifasciata in this spot, but I am concerned about whether the full sun in winter will harm it. I am also concerned about frost, but when I saw it planted outside at the hotel it made me think this is maybe a non-issue (or else maybe they cover it when a frost is expected).
Can I plant Sansevieria trifasciata outside in SoCal in a spot like I described?
