I'm not really seeing a problem - they do take time to fully develop. If you've had them flowering before, in that same container, they may also have needed a boost from some food as they died back, especially if they've been in the same soil/compost for a long time. They need a bit of help in containers, just like most bulbs would. Easier in the ground for that reason. They're much further on than mine though
It's a place where beautiful isn't enough of a word....
I live in west central Scotland - not where that photo is...
I think they flower from the bottom up, like Fairygirl says, it takes time. They look the same as mine so I shouldn't worry. I also find that the flower heads get so heavy, especially when grown in containers, that they flop and need staking.
They look fine to me too. Mine are similar. Most were originally bought as forced/ prepared ones and grown indoors the first year, but they've been out in the garden for a lot of years now. I like the more open-spaced flowers better than the tight-packed ones in the bulb catalogue photos.
Doncaster, South Yorkshire. Soil type: sandy, well-drained
