We have a beautiful and very old hollyhock tree in our front yard. My mother in law bought this property in the early 60s and planted the tree sometime after she bought it. There are also hollyhock flowers that come up every year all over the property. She passed away recently and it means so much to see her beautiful flowers. Are these two plants related?

Hibiscus splendens is found only in Australia. It was described by Charles Fraser in 1928. He wrote of it "This I consider the king of all the Australian plants I have seen. The flowers are of the most delicate pink and crimson and literally cover the plant"
