Answer: The answer to your question can be quite complicated, but in a nutshell, plants respond to light levels and temperature as they prepare to bloom. Yours probably just arrived from the nursery where they were receiving perfect environmental conditions and were at the peak of bloom. The act of transporting them to your local garden center and then to your home probably interrupted that process (because the growing conditions were slightly less than perfect) and your plants were set back a bit. They will probably drop all their buds until they become established in their new homes. At that time I suspect they will develop healthy new flower buds so they can treat you to their beautiful blooms. In the meantime, water them regularly, provide as much direct sunshine as possible, and prune off any dead flower buds or stems. Your plant will flower later this summer. Enjoy!
