Answer: Caryopteris usually blooms over a long period, summer into fall, but this really is too early for it to start. I do not know why it would be blooming already unless as you surmised it has been somehow pushed, perhaps it is a plant the retailer carried over from last season or it was kept in a cool greenhouse and then not trimmed back hard this spring. With a new plant, I think it is better not to cut it back because it needs the foliage to have the energy to root and become established. Next spring you should cut it back quite hard to remove winter damage and also help promote branching. This also seems to delay flowering a bit.
