Hi Judi! Great to have you onboard!
It can be frustrating, can't it? I've had phals skip a blooming season for no apparent reason when their neighbors are going nuts with blooms. Or sometimes, they are a type which just doesn't bloom at the same time as the others. Some like to bloom during the summer--don't know about yours.
So all we can do is be sure they have plenty of light and a warmish location. They will bloom when they are good and ready. ha
Any hints of spring where you live? Here there is still deep snow, but the days and longer and the light is stronger--so there is hope!
