What type of hibiscus are you referring to? Some are cold hardy to zone 5 or lower and others are tropical.

Tropicals do best kept above at least 45-50 degrees. I winter tropicals at 38 degree minimum low in the greenhouse and they survive.


RE: hibiscus minimum temps

i do not know the type, is there any other way to know if it is the tropical kind?

RE: hibiscus minimum temps

Since you say it as labeled as a tree hibiscus, I'm betting it's a tropical.
All tropical hibiscus are the species "Hibiscus rosa-sinensis." The plants themselves look similar; it's the flowers that vary.
If you still have questions, post a pic of the whole plant.
