Anybody Know The Name of This Plant?

This weekend is loaded with a list that has me running ragged. Today - I will be running the roads that will consist of hitting Maryville - Knoxville - Lenoir City - and then back home, again! Going to pick up Jen, Wayne and Austin Greene. Bringing Wayne and Austin back to the house to spend time with Dwayne. Taking Jen to shop for Khaki pants for her new job at Food City. Charlotte's having to work for a co-worker today at Turkey Creek - where Jen and I will be shopping. One of her co-workers just had her father pass away a couple days ago. Jen and I will meet up with Charlotte after she gets off of work. And then - the guys are meeting us in Lenoir City for a night out for Dinner at Angelo's! Can't wait! But after searching the net and my book of East Tennessee Wildflowers - I cannot find information on a flowering plant that has shown up in my yard. So - I got out there this morning and took pictures. The flower is about 4-5 inches long. It blooms out white with a beautiful purple that graduates down the inside of its throat. But the real kicker - it has the most wonderful - intoxicating - perfumed scent!!! I've found two on the property - so far - here in Loudon, Tennessee. One popped up next to our Pink Lady Apple tree - and I won't let Dwayne touch it! I told him to leave it alone and let it make seed. I will MAKE a special home for this gorgeous Perfumed Stranger! If anyone knows anything about this plant - please let me know! Click on the photos to get a larger view.
