Everlasting Sweet Peas

[Jennykenny]

Do you chop them down after they finish flowering? I'm trying to grow overhead 'rails' of plants in my small courtyard garden with vines, roses, jasmine, clematis etc to give it natural shade, running from one side wall to another.
I know they have no scent but they look pretty and are easy to grow.

Irrespective of the exact variety, the RHS website says "cut back to ground level in autumn".
