Only a few Tulips of the same type have bloomed...

Hi,

Has anybody else had a poor show for Tulips this year? I've had some yellow frilled tulips bloom but some have stayed in bud and look like they are JUST about to burst into bloom, but there seasons passing. I think they're late April varieties.and now i think they won't bloom. Same for orange parrot, yellow rose tulips (i think it's called that) and queen of the night which has come up stunted and some have tiny buds.....:( I've attached pictures... There's not been much sun here in Leeds and it's been hail stoning here today. I wonder if that's one cause... I'm not sure why half of them have bloomed and half haven't, even if they're all the same variety eg orange parrot.

 

I think due to the cold spring, well its been a cold one where I am, there is still time for the later varieties.

When are you looking only they close up at night and open up as the temperature rises.
I don't see anything wrong in your pictures.
