I planted a Black Lace elderberry 5 years ago. It has never grown any larger than the day I planted it. It does produce leaves and a few blossoms, but does not grow. What could be the problem?

Evidently, the growing conditions it is currently in are not suitable. It may need to be moved elsewhere. Give it plenty of sun in well-draining soil. Transplant now, getting as much of the rootball as possible, or wait until fall.
