Hibiscus rosa-sinensis
Jorun, here are a few photos of the Hibiscus we have on our front, south facing, balcony.
The first photo is of one of the flowers we enjoyed seeing while having our summer breakfast on the balcony after our morning swim in the sea.
The second photo shows the balcony as it was on the 9th of January.
I didn’t snap the Hibiscus as there was no snow in that corner.
The third photo shows the Hibiscus plant as it is today
I think your Hibiscus should continue its peripatetic life
