Thank you, and thanks @B&B Happy goats and @Alaskan@promiseacres my condolences. Sounds like a life well lived.
If these are the typical greenhouse grown hibiscus and Boston ferns, then yes, most emphatically yes you need to bring them in. I vividly remember the smell of a greenhouse full of Boston ferns when the heater failed on a freezing night. (Fortunately, the root balls didn't freeze, so the crop was salvageable, but we had to cut all that frozen foliage off)
On the other hand, there are cultivars of frost-hardy natives that are usually planted in the landscape, but you don't usually see those sorts of ferns in hanging baskets, for example. The Hardy Hibiscus have dinner plate-sized flowers, and are labeled as such.
It's a boston fern so I brought it inside today. I think i'll put the hibiscus in the greenhouse...there are too many to keep inside, plus I noticed today that their pots are filled with fire ants
