: 50 is pretty much the lowest temperature that a hibiscus will tolerate. Anything temperature near or less will cause the tree to become stunted in growth. If the temperature is to drop to 50 or below, take it in for the night and move it outside in the morning, to be safe.

It may depend on the hibiscus ...
Living in the tropics we have hibiscus in the yard,
and the night temperatures do drop into the lower
50s in winter sometimes, rarely into the upper 40s.
Never seems to have done the hibiscus any harm.
These are planted in the ground, so their roots don't
get as cold as they would in planters, but I do seem
to remember seeing hibiscus (also in ground) in areas
higher up where the temperatures occasionally drop
below freezing.
