Rosemary is really not a houseplant. In areas where winters are
too cold, it can thrive in a greenhouse with climate controls set
for plants instead of humans (not merely temperatures but also
humidity).

For what it's worth, the plant is happy growing along rocky coasts of the
Mediterranean. My suggestion would be to buy another plant take it to
central or southern Italy until spring.



On the other hand, you had a plant that seemed to do well in your
kitchen for several years and then failed. Then, its replacement
also failed. If nothing else changed during those years, you might
have a gas leak.

I had an EXTREMELY small gas leak a few years ago from my furnace. I could
smell it occasionally as I did things in the basement, even though the odor
was very slight. The result was endless problems keeping tiny seedlings
alive under lights about 15 feet from the furnace. The gas company came over
and waved some sort of device around, pinpointed the source (a loose supply
pipe), fixed it, and the plants were fine afterward.

Some stoves release just a bit of gas before the flame kicks in. Might be
worth looking into.
