The Luna Rose Hibiscus should not grow for me in Central Wisconsin (zone 4a) but it does and with great display. My soil is too sandy and extremely acidic, the climate too harsh. I cut it down every Fall to about 6" and in mid June, about the time I am ready to give up on it and dig it out, I finally start seeing the beginnings of new growth. The flowers are enormous. This is my 3rd year of growing them, they are ignored and keep on growing.

Doesn't get better than this. Bought this at Lowes at end of Summer 6 yrs ago, and it dies back in 0ctober to nothing. In May , green shoots will sprout out of last yrs dead looking wood spikes, you will think it has died, but be patient, by August you will see the dinner plate blooms, showing its magic. Likes morning shade & afternoon sun in our yard, facing west.Not finicky , but I have read it likes moist soil, I never water it myself, it has returned every year after many snowy winters, in RI.
