Hibiscus rosa-sinensis 'New Idea'
This is a 1990's Australian Hibiscus of Greg and Julie Lindsay (Hibiscus Paradise Nursery) from 'Pro Legato' x 'Harvest Moon'.
The carmine red flowers are occasionally splashed with white and they last for 2 to 3 days.
It needs to be grafted for best growth.
I currently don't have any stock of it available
