I haven't tried, but even in San Diego I see them struggle unless they have great drainage and get ZERO frost near the coast. Just a few miles inland, they go bare in winter and struggle to come back in the spring. I'd think you would need superb drainage or even better, a slope, and pretty much no frost in your area. However, you indicate you're Zone 15, so you must be a little too far inland. You may have some luck in containers under an overhang, even if left outdoors.
