If you manage to grow one of these you will never be with out it, there are loads of viable seeds per plant. I found an old brown envelope with collected seeds in the bottom of some pots a few weeks ago. Loads had germinated without soil!
I've potted them up into medium sized pots and they will be planted out when big enough for flowers next year. I think they have quite large tap roots so I won't leave them to long in the pots. I've seen the purple ones in hedgerows, you can get them in white as well
