Oh, I was quite disappointed when I read the original post title - I thought maybe Loz had a huge rhubarb she could grow a climber up!! However, it seems not - seemed a good idea - imagine the rhubarb crumbles!! I think indeed it may have been overcropped last year, and thinks it had better set seed before it dies - it will not die if you remove the seed head as the others have said, and leave it alone for a while.
Regarding the climber, how much space do you need to cover? Some of the bigger clematis montana are wonderful for that if there is the space, but they do get very, very large and heavy - we have 3 and they are about to flower, given a few hours sun - please! Climbing hydrangea is good too, needs help, it won't self cling to start with, but it a lovely plant. Some of the more vigourous climbing roses are good too - but much depends upon the area to cover and the angle - south, north or whatever.
