Put some seeds in many years ago and got no plants showing, then this year they show there faces, so the seeds must have stayed dormant for all those years. Thats nature for you.
This is one of my favourite flowers and I have them popping up in my garden all the time.. because of our 'mild' winters we can have them flowering about 9 months of the year.. I find that the more they seed down the lighter the colour gets .. so must get some fresh seed and see if I can get any of this lovely dark blue..
