how long to flower?

[Fluorescent green]

Hi

I have some pansys in various places, and they look great. I am not sure what variety they are, but will they carry on flowering; I have the 'in bloom' judges coming on the 19th July.
Should I be looking to dead-head them, or gather seeds? If I just leave them, will they just carry on a little longer, and then over winter and flower again next year?

If you dead head them they will carry on flowering through the winter and into next year. They tend to get a bit straggly after a while but I think if you dead head them they stay a bit more compact.
