Sorbus (Whitebeam)

There were no flowers on my whitebeam this year, though last year's display was brilliant.  Noticed similar trees in Sainsbury's carpark had no flowers either.  Is there any reason for this?

Mine didn't flower either this year. The only thing I can put it down to is the weather. The acorn and beech nut formation also failed this year and again the weather seems to be the cause. Looking on the bright side (I hope) the tree has had a rest and lots of water so here's hoping for a bumper crop of flowers and berries next year - weather permitting! 

I have 4 whitebeams. 3 had no flowers at all and one had plenty

Thanks for the replies.  I am pleased it wasn't something I said!!  Hopefully the tree will bloom doubly well next year.  Thanks again
