Moonflower Thorn Apple

OK we confirmed, it's my Aunt Judy's flower, but my grandmother took the picture. She'll get some pics of her Florida flowers if they survive the heat. She has 6 plants growing as of last week. It's been hot with no rain.

ALice - It only blooms at night, is very fragrant, but then by day time the next day, that flower is done/spent/dead. There are many many blooms and this plant is on the invasive side in Northwest Florida. My grandmother reports that it will take over an entire bed if allowed.

My grandmother's sisters, all growing up in Cadillac, Michigan in the 1930s and 40s had these "at the farm" and other houses they lived in in Michigan. My grandmother has lived in Valparaiso, Florida since the 1960s and collected some seeds and cuttings from the plants in Michigan. They grown in Florida. She's saved seeds for me and I've tried growing them but they never grew (In Atlanta, Georgia). She says she will try to get some starts for me. I will have to plant them where the dogs do not go though. I seem to have a dog who thinks she is a billy goat who samples everything I plant, most recently cucumber leaves.

Thanks for the ID Dan. Isabela - these Moonflowers are often confused with Morning glory plants, but they are not a vine, but a bush-like plant.
