Agapanthus Query

I would be grateful for some assistance with a particular issue I have with my agapanthus plants and flowers. 
I have enclosed some photographs illustrating issues with thickened flower stems (over 2 inches wide!) and oversized flowers and ridged leaves.
This is the second year that this has happened and has not been restricted to just one single plant.
Any advice would be much appreciated. In particular, do you think that this is likely to be a permanent change or will the plants revert to their normal habit in future years?

    My suspicion might be damage damage to the growth point early in the growing season but as this has happened two years in a row such damage would be a very unlikely coincidence. Further, judging by the width of the leaves, I suspect these to be evergreen rather than deciduous varieties which again makes physical damage less likely.

    Irregular watering can also do strange things to the plants but this usually takes the form of flower heads almost snapped at the neck or kinks in the flower stem with mini flower heads breaking through.

    Did you buy the plant from a specialist grower? If so, I would send the pictures to them and ask for their observations.

    I'd guess at fasciation and will probably be ok next year. But it's really a guess.

    I am a keen apapathus amateur.  I guess fasciation too.  This is often said to be due to an insect attack at an early stage of growth.  But all I know is that it happens more often to my evergreen agas, which these are definitely.  It is, for me, usually the flowers that are affected - flattened stems and deformed flower heads - much worse.

    Come the winter, protect from frost.  Mine spend the winter in a cold greenhouse that can go down to the same as outside, but not for so long.  They get zero water all winter.  Water, clean up dead leaves and put outside as soon as sunny days return.  But be prepared to rush them back to cover when frost is forecast.

    My deciduous agas in pots survive outside, but are moved closer to the house.
