I reckon it'll be fine hollie. Decent rootball and all the normal procedure. I think you'll get flowers too - they're quite forgiving usually
I started out with one blue one and one double white one about 8 years ago. I now have 20 or so self-seeded, but they are all dusky pink! I must have weeded out easily a hundred or so by now.
I agree with Fairygirl though, if you're going to move one take a big rootball with it. Mine always swoon like a Victorian miss immediately after being moved and need plenty of watering in.
I find the best way to germinate them is to sow immediately the seeds pods split open in the Autumn in a seed tray and overwinter them in the tray. They can be a bit stubborn if collected and then sown in spring.
