Answer: How disappointing! Your snowball bush should bloom in early spring. It's possible it is still maturing and once it reaches the right stage of maturity it will bloom. Snowball bushes are typically pruned immediately after flowering is finished which gives them all summer to develop flower buds for the following spring. If yours doesn't bloom next spring, prune it back by one-third in early summer. The new growth it develops should include some flower buds for the following springs' display.
