It's not unusual for them to flower but I wish mine didn't!
The flowers are the highlight of the display though and the bees love them.
Mine are mostly kept outside all winter but some do better with a cover or shelter of some sort over them. They don't need frost protection but persistent rain can cause rot problems so a rain cover that allows good ventilation is ideal.
If you can keep your head, while those around you are losing theirs, you may not have grasped the seriousness of the situation.
