I planted a Seven Son Flower tree last October. The soil is heavy (clay). I amended an area at 5 ft-6 ft in circumference and installed the tree, which is at 6 ft this year. The leaves are browning around the margins and are slightly yellow compared to last fall. Any suggestions?

Maybe try a french drain around the tree. About 2-3 ft out from the tree, dig a trench about 10-12 " deep. Then dig a trench leading away from the tree. install perferated tubing and cover with loose gravel, or at least put loose gravel if you choose not to use the drain tubing. Make sure you put at least 6 inches of the gravel. Then cover with soil. That should help the soil drain well. Let us know if this helps. We saved a japanese maple with this method.
I bought 2 trees a while back and they are suppose to be Seven Son Trees. They were suppose to get big and have red flowers, but one is short and doesn't look very healthy, and the other has gotten bigger and last year and this year it has White Flowers on it. I was told since I bought them about 8-10 years ago they were a fairly big tree with red flowers on them. What do you say??
"Seven-son flower" is a large shrub / small tree in the honeysuckle family which has white flowers that are followed by showy, cherry-red seed capsules.
Consider your soil fertility and water management for improving growing conditions to promote growth and flowering.
I would like to purchase this plant for my new garden. There is conflicting information about how tall it grows. I need to keep it to a maximum of 12 to 15 feet, accomplishing this through pruning if necessary. Is this possible?
It gets from 15 to 20 feet tall at maturity. It's best to choose a tree that won't exceed your height desires. Then you don't have to keep it trimmed.
