7 leaves on rose stems

Am I right in thinking that once stems produce 7 leaves they will not produce flowers and should therefore be pruned out?

I read an article somewhere and Alan Titchmarsh was suggesting that roses will even survive and be fine in heavy clay soils that are prone to flooding even for several days at a time. Is this correct?

Thank you everyone. I must rush off now to try and make the garden look a bit better after all the wind and rain we've been having!!!

 

Hi OakdaleDave.
Long answer short.
7 leaved roses are wild roses that have broken off the rootstock below the graft. Roses are grown on rootstcks for vigour but their attributes are grafted on. Garden roses have 5 leaves.
Wild roses will flower, but they might not give you the attributes you want. They are just lovely in the hedgerows but maybe not what you want in the garden unless you have a very big place.
Pruning out the suckers is not just a matter of cutting them off. They will just come back. I'll leave it to the experts to tell you how to get rid of those suckers.

As for clay, yes roses love to grow in it. I don't know about flooded for days at a time.

 

Well there you go - Oakdavedave.
I told you the experts would be along.
Follow Woo's advice and your roses will be no problem.

 

Having taken a closer look, I notice that on most of the stems they have started with 5 leaves and then as they have grown taller they are growing 7 leaves on the same stem! Now I AM confused!
