Cindy,
If it was at the base of your house, on the South facing side, with a stone path, raised bed, I'd say, Give it a shot and leave it out...
But, it looks like it's out away from the house,
which means no protection if some cold snap were to happen..
Not sure exactly, anything I just read says to bring them in that even
zone 7 and 8 are iffy's!!
Now the kind I have, is a different variety, and it's a house
plant, but I think the kind you have you can take it in for the winter and put it in some kind of...peat moss/vermiculite/ or sawdust.
And keep in a dry and warm(ish) area, to like insulate them.
Not 100% sure, hopin' someone in your area will come thru with a some other hints for you???
