Can anyone tell me what tree this is? We have several growing around the perimeter of our yard, on the edge of a scrubby/foresty area. The tallest one looks to be around twenty feet tall. The soil is sandy, somewhat moist, with a boggy area maybe a couple hundred feet away. We're in coastal North Carolina. The flowers have a really beautiful, sweet fragrance. I've included flowers, leaves (or more likely one divided leaf), and a seed pod from last fall. It's blooming right now. Thanks!
