Tropaeoleum speciosum - My neighbour wants to grow this in her garden - I have loads in mine... How do I propagate it?

I would have thought either by seed, collected in the autumn or by nodal cuttings. I suspect it has seeded itself in your garden, if you have plenty. It may also be possible to take root cuttings. Alternatively, could you dig up a small plant from your garden?
