A weeping form of Cercidiphyllum japonicum, introduced by Theodore Klein. Theodore found the tree at the nursery of Jess Elliot in Southern Indiana across the Ohio River from Louisville. The tree was originally known simply as 'Pendulum' for its weeping growth habit. There is a gorgeous specimen of this cultivar in Cave Hill Cemetery in Louisville. The plant got its name when Bob Hill, Tony Avent-the owner of Plant Delights Nursery in Raleigh, NC and Mike Hayman were taking a tour of Cave Hill. Mike commented that the name should represent the graceful growth habit of the tree, and Bob said, "How about Amazing Grace?". Theodore objected to the name at first, but eventually relented!
