Regarding the ideal temperature for growing this plant, which is also known by the name of anti-mosquito geranium, it must be known that it can withstand temperatures perfectly well as long as they are not excessively cold.

However and in winter times the room or the space where it will be placed has to have a rather warm temperature.

It is important to emphasize that if you want it to flower throughout the year, it is necessary to provide all the light it needs for its full and normal development. In this case, a lamp could be used as a substitute for natural light and kept in a warm place.
