This is only the 2nd year I've had it but last year it bloomed all summer. This year I had a lot of blooms at the beginning of the summer but then nothing. Why isn't it continuing to bloom? Thanks.

A lack of phosphorus, which is responsible for blooming in plants, could be the issue. If your plant is lacking phosphorus, use a phosphorus rich fertilizer or add some bone meal to the soil.
