Hibiscus flourishes in Malta. Is it ok to propagate or plant hibiscus in December? We have a temp of about 16 C on average. As I walk along the streets, I notice beautiful flowering hibiscus in front gardens of houses. It is easy for me to ask an owner for a few cuttings and plant them in my home. I have a small back garden. I do not possess knowledge of propagation, but would love to have one in my garden. They are such a lovely sight.
