Everlasting Sweet Peas

I never have much luck with growing the scented vari coloured sweet peas. But this plant of the everlasting variety just keeps on flowering every year. Having written that it will probably be a curse on next year.

We waited all day for heavy rain but only had a couple of 2 minute showers. But I am risking not watering the garden this evening as I am sure there will be more overnight and tomorrow.
