Perennial hibiscus has similar shaped flowers to the bush, but they can be more than twice as big, growing up to 10″ across. They have a more limited color selection (pinks, reds and whites) but the extra-showy flowers are worth it!
The perennial version requires more water than the bush, and dies down to the ground in the winter.
