You have hibiscus in Canada????? Gorgeous!
That is a perennial Hibiscus. It's a real traffic stopper!
Do you dig yours in the winter and bring inside or just protect it? Gorgeous! I'm in ND, have seen them at Lowes and Home Depot in teh summer.
It lives in the ground year round. We usually get a nice 3 foot blanket of snow which I'm sure helps protect it.
