Hibiscus plants always make me think of tropical islands, which is why I have them all around my yard. 

This is the plant which caused my MIL to exclaim “But that’s marijuana!” during a tour of the house and gardens via Skype.  Actually, it is a Swamp Hibiscus, which I think is a Southern native. I found two last summer while out shopping with my mother and this is the first time they have flowered.
