Saroj ji leaves are different, staminal tube shorter and most important leaves are almost entire, epicalyx fewer.

For me it looks Saroj ji is correct as there are innumerable varieties and cultivars available . : https://www.google.com/search?q=Hibiscus+rosa-sinensis++in+toptropicals.com&source=lmns&bih=657&biw=1024&hl=en&sa=X&ved=2ahUKEwjQxcm-yMrvAhUDXisKHZA7AIAQ_AUoAHoECAEQAA

Sorry friends you may ignore membranous toothed leaves of H. rosa-sinensis (vs thick entire leaves of my plant), linear 6-9 epicalyx in H. rosa-sinensis (vs 5-7 triangular-lanceolate in my plant). I would go with cultivar of H. arnottianus (or H. denisonii, which is of course an ambiguous name) , which is almost as widely cultivated as H. rosa-sinensis.

I am sharing more pictures to make things more clear.
