Nice plant Scott. I don't have one, but plants like that, I keep in a pot, just in case since we can go into the upper 20's here. That said, I have some cold sensitive plants in the ground that have tolerated temps way below the temperatures they are stated to take, usually around 50°.
My theory is these cold sensitive plants tend to adapt as they age to cold temperatures. I find it takes time to find the right spot for it anyway, bright shade, under tree cover, with morning filtered sun is best. These plants come from greenhouse protection, so getting one now gives it time to adapt to outdoor living, and then give it at least one winter, then try it in the ground next Spring. I take a clipping off my favorites just in case.
I have plants like Monstera deliciosa in the ground under an oak, that states temps not lower than 50°, it showed no problem down to 32° briefly, this winter, but I did put a beach umbrella over it that night, still many many nights for hours below 50°. Some Calatheas and Aglaonemas are also outside, although they're in pots, but they also state not below 50°, and they were out many nights in the upper 30's and low 40's. The Aglaonemas even the 32 degree nights. All these plants are in spots that are north wind protected, areas under the cover of trees, most get East sun exposure to warm them up in the morning. No direct sun.
Hope this helps, my zone is a hard one, since we can drop pretty low some winter nights, I don't think you ever go below freezing there. Some plants though won't do well with too many nights below 50°, after experimenting I know which plants after at least one or two winters can tolerate colder temps, and which plants can't, especially plants I lost to cold.
. I passed, they didn't look near as nice as the photo you posted. My local Home Depot doesn't have anything like that.
