When do potato plants flower?

My Belle de fontenay (earlies )potato plants which I planted in dustbins in march with lots of manure are now very very leafy and look quite healthy to me.
I haven't seen them flower and i am not sure when they should but I looked at the today and I am not sure if they have tried to flower and have haven't quite made it.
When should they flower and is it a bad sign if they dont?

 

Some flower and some just form flower buds that drop off.

Not sure why some should not manage to flower, but I guess its in the breeding.

 

That's alright then as long as it's nothing serious. When do you think they will be ready?

 

Depends which type they are - there's early crop, summer crop, late crop - so on and so on! You get the time of the crop from the type. Then around that time, just plunge your hand in and see what you get! Bit like a lucky dip!

 

I have first earlies in at the mo and the leaves and stems look very large, strong and healthy. The packet said they were the Duke of York variety and would be ready to harvest in June/July so I'm not panicking yet that I have no flowers. I grew some potatoes last year which turned out ok and did flower at some point.

 

Hi. I planted mine(earlies) in mid April. I don't expect them to flower/be ready until sometime in July.

Thanks for the replies.

I have noticed this week that there are now some flowers developing , though still in their buds at the moment. I have had a bit of a feel around in one of the bins but couldn't feel much , so I will leave well alone for a bit longer.

 

Hi again. I just noticed that mine too are showing flower. Much earlier than normal, and I'm wondering, could it be the recent hot weather ?

Cheers...freddy.
