Urgent Tree for Planting

This was a small size plant/tree height was roughly to the height of your knees! It was planted in the front and thrived for years! This winter it bloomed flowers as you see in picture! but during april to june, the leafy beautiful leaves spread out and the size was to hard to hold upright in the front of the house! *** 2 days now. I removed it and planted it in backyard so it wouldnt block the pathway to the front door! problem is= the soil in the back is clay soil and even thought i put black earth the clay is no good for the roots and it is not happy!! I HAVE NO WHERE TO PLANT IT ANYMORE??? and the spots i know are good for gardening have plants!! Our backyard has drainage issues and the soil turns into clay. as its on a slant more likely you wont have that issue DO U WANT TO GIVE THIS PLANT A HOME, It can still be saved as the leaves are drying now... but asap to replant! msg me to ask more questions
