Cheers for that Smudge. I shall now leave it to be killed off by the frost and hope that it does indeed reseed and I have some new ones next year. It was a very worthwhile plant and gave loads of colour against my roses and the fence and only this week has it showed signs of dying.
On this subject,does anyone know the species name of the morning glory that grows wild all over Spain,It doesnt set seed,but roots where stems touch the ground.
