We finally figured out what the blooming vine was at the back of our yard....It's Wisteria!!! Thank you to Allyjo for suggesting looking up native vines of Indiana!! It is beautiful and smells heavenly. It is probably technically considered a weed, but isn't morning glory considered a weed too? I love blue morning glories. We started some in jiffy pots and I will be planting them this week. I just have to pick where I want them. Have a great day!!!!
