Hi Lorraine, welcome to g o y, usually a rose has 5 leaves, but when you find 7, it's usually from a sucker, do the shoots with 7 leaves come from below soil level?, which will mean they're below the graft, and are suckers, you should remove them,a s a p, {they sometimes have a lot more thorns on the stem as well} they will be stems that have reverted to the briar stock, onto which the variety has been either budded, or grafted, Derek.

Although, some of the more robust cultivars do have the occasional seven leafleted leaf, so don't worry too early.

Thank you both Derekm and Worthy1 for your comments on my climbing rose. Yes the 7 leaf branch is probably a sucker as it is right at the bottom of the rose. Thanks. Lorraine.
