I would say the answer is 'probably will be fine'. The more light, the better (at least on your porch), and if the temps get too cold, I assume your plant is potted and you can bring it inside for a day or two until it warms up again.

My various sansevieria trifasciatas love the summer heat and humidity of Louisiana. Of course I bring them inside at 50* and below. Especially Lillian True or fasciata. I am told that all variegated sans are tender.

I have several sans and they have been outside for over a month now. I'm in zone 6 and they are doing great. Two are in bright shade and one gets afternoon sun and I've never had a problem. I'll bring them inside in the fall and in the house they don't get too much direct light either(they're in bright shade inside too). I can't even remember the last time I watered them and they seem to love it:) They put on a lot of growth this year which I'm very excited about. Good luck with your new plant..sharon

I kept a group of mine in semi-shade all winter, and we had a hard freeze this year, they had a plastic hard cover over them and they were on a north wall, I kept them very dry, and they did just fine, which was another surprise. I learned nothing is written in stone. The plants at the Huntington Gardens did not do so well.
I will try some in open run this year just to see what happens. Norma
