@heavanet- I think that you are confusing the state that has the hibiscus as its state flower with Florida, but it is an understandable misunderstanding. Hawaii's state flower is the hibiscus, but it's easy to see why you confused this with Florida since it is also a warm, sunny state.
As far as I know, the orange blossom has always been the state flower of Florida. It's easy to see why, since oranges are a common crop in the state. It is also easy to remember that the orange blossom is the state flower of Florida, since one of the nicknames for the state is "The Orange State."
